She is the only duo character to be a friend of Nutty.
Lammy's perception of Mr. Pickels is similar to that of Calvin's perception of his stuffed tiger Hobbes in the "Calvin and Hobbes" comic strip, where Mr. Pickels appears as a character when she is the only one perceiving him, and as a normal pickle otherwise. She is also similar to Jonny and Plank from the Cartoon Network series "Ed Edd n' Eddy".
The episode All Work and No Play is the only episode where she appears without other female characters.
She is (possibly) the sixth mentally unstable character. The other five are Flaky, Flippy, Russell, Petunia, and Nutty. Her possibly having schizophrenia, Flaky having general anxiety disorder, Flippy and Russell having post-traumatic stress disorder (insanity in Russell's case), Petunia having obsessive-compulsive disorder, and Nutty having a sugar addiction.
Lammy and Mr. Pickels are the 21st and 22nd characters to come back to life after dying, as they both died in All In Vein and came back in You're Kraken Me Up.
She is the only female character who has not cried yet.
Lammy and Mr. Pickels are the only characters not to appear in an irregular episode.
Like other characters (excluding Russell), she speaks in gibberish, but her gibberish consists of "bahs" rather than the typical HTF language. This was possibly done to differentiate her from the others, since she is a new character.
There is some evidence that Lammy may have schizophrenia.
When Lammy gets shocked by Lumpy's tazer in A Bit of a Pickle, a crack can be seen in her skull when her skeleton is shown. This hints that she may have a mental illness.
In the same episode, the moral at the end is "We don't see things as they are, we see things as we are.", further suggesting the possibility of her schizophrenia.
If Mr. Pickels is not just an ordinary pickle, it is unknown how he reached her in jail in the same episode. It is more likely that he is imaginary and that her mind had simply turned a completely different pickle into him.
However, she does not have any of the symptoms of schizophrenia besides debatably hallucinations.
In season 3, her and Mr. Pickels' alliterate sentence is: Long lasting friends don't tend to be fickle, more likely, they would love to laugh and tickle!
Lammy and Mr. Pickels' actions may be a reference to Kid vs. Kat, since Lammy is always being blamed for what Mr. Pickels does, similarly how Coop is blamed for Kat's actions.
Lammy is the only character who rarely dies who is not considered an adult.
She and Flaky have yet to find a love interest/boyfriend or be in a Love Bites short.
Lammy, along with Mr. Pickels, are the only characters to debut in 2010.
Her name and species may have been inspired by Lammy the Lamb from the PaRappa the Rapper series, who first appeared in UmJammer Lammy.
Her and Mr. Pickels' appearances are a bit similar to the likes of Cream and Cheese from the Sonicseries. Both are young, cheerful females with small male companions wearing formal clothing, but with different kinds of alliances.
She dies in 3 out of the 7 episodes she appears in. (4 if one counts Breaking Wind).
She dies in every episode that she has a featuring role in.
Lammy is the only character that rarely dies, who is currently dead.
She is the final main character to die in the Internet series and doesn't appear in the shorts or the TV series.

Lammy is one of the few characters who have not been killed by an animal. The others are Pop, Splendid, and Flippy.
Lammy's bow usually changes its position when she turns to the other side; much like Lumpy's antlers, 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.
She, Toothy, and Mime are the only purple characters in the show.
Lammy is one of the eight characters wearing clothes. The others are Mime, Disco Bear, Pop, Flippy, The Mole, Russell, Handy, and Lumpy.
