Lumpy is similar to Homer Simpson, as both are known for their stupidity, both have held many occupations, both have been shown to eat a lot, and Lumpy's relationship with Cuddles is somewhat similar to Homer's relationship with Bart.
Lumpy is also the name of several other fictional characters.
Lumpy, along with Lifty, Handy, and Cuddles make a cameo appearance as a totem pole in Gundarr, another Mondo Media show.
Lumpy has been shown to enjoy eating meat, which is odd since real moose are herbivores. Then again, the characters of Happy Tree Friends are portrayed as mostly human in behaviour, which this may be an example of.
Most of the time, Lumpy's mismatched antlers change positions, although there have been occasions where this does not happen. This is mostly due to laziness on the animators' part, similar to how Toothy's teeth change from his usual teeth to the standard buckteeth. This goof is easier to notice when Lumpy is looking back and forth.
Currently Lumpy has spoken English more than any other character in the show.
Although Lumpy appears to be an overall nice character and usually does not kill other characters intentionally, he seems to be one of the most hated characters in the show due to his stupidity.
Throughout the entire series, Lumpy is always seen with one of his antlers up and the other antler down. There were only two instances where both of Lumpy's antlers were pointing at the same direction, one was in From A to Zoo and the other one was in Concrete Solution.
Lumpy may also be based off Goofy from the Mickey Mouse cartoons, as both have similar personalities, voices, and are the tallest of their respective groups. Ski Patrol, which stars Lumpy, parodies the old Goofy shorts.
The Camp Lazlo character Scoutmaster Lumpus may be a reference to Lumpy. Most importantly, Lumpy had the position of scoutmaster in Take a Hike.
In the "Rocko's Modern Life" episode "Bedfellows", a character looking almost exactly like Lumpy has a car dropped on him. However, this episode was made in 1993, so this is only a strangely accurate coincidence. Also Lumpy may be based loosely on that character.
In the Second Servings DVD, Lumpy has his own brand of sponge cakes called "Holiday Kringles", which look like Twinkies.
Despite living in a trailer most of the time, he seems to be well off, even rich. Consider the following facts:
He owns an amusement park named after himself.
He owns a circus.
He owns a toy store which boosted its profits from selling toys and Toothy's body parts.
He owns an elephant.
He owns a house with a giant hamster cage.
He owns a motorcycle in addition to several vehicles.
He owns a farm where he grows corn and staffed with mindless workers that do not need to be paid (Pod Lumpys).
He owns his own newspaper.
He seems to have high paying jobs (particularly being a surgeon).
He has, at one time or another, employed practically all the other Tree Friends.
Lumpy, at one time or another, employed, served as boss to, was a superior to, or was in a position of influence to most of the other Tree Friends.
Lumpy has never been under the influence of another character in the work force.
Cuddles - Was employed as a daredevil in his circus in Mime to Five and as a reporter in See What Develops. He was part of a play directed by Lumpy in Class Act. He was part of a band where Lumpy was an influential member in In a Jam, where Lumpy alone took the decision to employ him. Lumpy was his scoutmaster in Take a Hike.
Sniffles - Worked at his newspaper in See What Develops and has a part in a play directed by Lumpy in Class Act. Lumpy was his scoutmaster in Take a Hike. He was part of a band where Lumpy was an influential member in In a Jam, as could be seen when Lumpy was seen as the one who decided to hire Cuddles.
Lumpy is the first character from Happy Tree Friends to wear pants, though they are the same color as his skin.
According to the commentary from Spin Fun Knowin' Ya, Lumpy's original antlers were bigger and normal, but the crew decided that he looked too much like Bullwinkle (whom he is based off), so his antlers were made smaller and turned in different directions.
Lumpy wears an invisible T-shirt that blends in with his skin. When he takes it off, he can be seen with a tan line, nipples, buttocks, and genitals. He accidentally flashes Giggles in both You're Bakin' Me Crazy and Let It Slide.
Lumpy often shaves his face, even though he physically does not have a beard. However, in the episode Double Whammy Part I he had a beard while he worked as Flippy's psychiatrist. From this, it can be assumed that his natural hair color is black. This is proven false as he had a white beard in Just Be Clause.
He is the only character apart from Lammy and Mr. Pickels who does not appear with mitten hands. He always has fingers.
Lumpy does not have a tail, which is odd as real moose have tails (though tiny stubby ones).
He has appeared in most of the Halloween episodes and has only died twice.
He has the highest kill count of the main characters by far. In fact, he has more kills than Fliqpy and Pop combined, the next two characters who have the most kills, one of which is primarily famous for the fact that he tends to kill other characters. Splendid and Petunia in Breaking Wind may have more kills than Lumpy, but this is debatable.
The only characters to not kill Lumpy are Flippy, Lammy, and Mr. Pickels.
Despite Fliqpy having a reputation for killing others, Lumpy has actually killed more characters in a single episode (Class Act, where he played a part in killing every main character at the time) than Flippy (whose highest kill in a single episode is 12 major characters in Remains to be Seen).
All in all, Lumpy killed someone 52% of the time he appeared, and he has 1.5 kills for every appearance he made.
Lumpy dies more often in the TV series than the internet series.
Lumpy has been the sole survivor of 14 episodes and kringles total. This makes Lumpy the most common sole survivor.
He is one of three characters to not have a heart-shaped nose. The others are Sniffles and Mr. Pickels.
Lumpy is one of the the four characters who stars in an episode with a large cast and survives while everyone else dies. The other three are Mime, Splendid, and Giggles.
Lumpy's antlers usually changes positions; much like Lammy's bow, Flippy's beret, Nutty's eye and candy, Russell's eyepatch and hook, The Mole's mole, Handy's tools, Sniffles' pocket protector, and Cub's diaper pin.
Lumpy is one of the four blue main characters, the others being Petunia, Sniffles, and Splendid.
Lumpy is one of seven characters not to have the same kind of eyes as the other characters. The other six characters are Cub, Nutty, The Mole, Lifty & Shifty (from the TV series onwards), and Mr. Pickels.
He is one of the main characters who do not die in their debut episodes, the others being Petunia, Handy, Lammy, Splendid, Flaky, Cro-Marmot, The Mole, Flippy, Disco Bear, Toothy (Debatable), and Mime.
Lumpy is one of the few characters to eat/drink the remains of themselves or another character, the others are Cuddles (thrice), Giggles (four times, one time offscreen), Toothy, Petunia, Nutty (twice, one time offscreen), Pop (Offscreen), Cub, Flaky (twice, one time offscreen),The Mole (Offscreen), Russell (Offscreen), and both sides of Flippy (thrice).
