In the Pop Corn edition episode of Spin Fun Knowin' Ya, it is revealed that Toothy had a tail enlargement surgery and is wanted for impersonating a dentist in seven states, and was last seen in Ohio (this may be a reference to Nuttin' but the Tooth).
Although Toothy doesn't have much of a concrete personality, Toothy's personality can be best described as "Cuddles' personality, but with different interests". He is also shown to be less mischievous than him.
There is a recoccuring goof with Toothy's teeth. In the early episodes his teeth would switch to the standard character's buckteeth as opposed to his huge, gapped buckteeth. This goof stopped appearing after the start of the TV series though it happens several times in Take a Hike.
There have been two times when Kenn Navarro took Warren Graff's role, the first being in Keepin' it Reel, where he played Toothy, and the second being in a A Hole Lotta Love, where he played Handy.
His Season 3 alliterate sentence is: "Using a toothbrush is tantamount for twinkling teeth". Also, the toothbrush is a reference to his name.
There is a Halloween costume of Toothy with a pair of scissors impaled in his eye.
In Spin Fun Knowin' Ya, Toothy was seen with two stray hairs on his head. They disappeared in all future episode, but stayed in his season 1 intro.
Toothy's buckteeth are normally longer than the buckteeth of other characters(hence his name). In some earlier episodes, he has his normal buckteeth, but they would change between being from his normal to short like the rest of the Happy Tree Friends. This was a goof, and was corrected during the TV series.
His appearance is similar to the Nickelodeon character SpongeBob SquarePants, as both have large gapped teeth and freckles on both sides their faces, and they both cry a lot. He is also similar to Timmy Turner from the Nickelodeon show The Fairly OddParents due to their large front teeth, purple-pink color, and because they are both accident-prone.
Toothy survives 16 out of the 72 episodes he appears in. If he survived his debatable deaths he would have survived in 18 episodes.
In the TV series, Toothy appears in all three episodes of "Deep Six" and "Behind The Eighth Ball".
If you count Autopsy Turvy (Double Whammy Part II) (although that was not a real episode), Cuddles, Flippy, Cro-Marmot, The Mole, Lumpy, Lifty, and Shifty have appeared in all of his TV series starring roles (since he only had one).
Toothy is the first character to die in the Internet Shorts , and thus the first to die in Happy Tree Friends (unless you count Banjo Frenzy). Similarly, he was the first (major character) victim of Fliqpy in the internet shorts and the TV series.
Toothy has a wide range of deaths; usually involving his eyes, his head, getting crushed, and disintegrating.
Toothy is the one of the two characters to be killed by every original character at least once, the other character is Lumpy.
Toothy has the worst survival rate out of all primary characters.

They are the only beavers in the show.
They both share the same voice actor, Warren Graff.
They both star alone in only two episodes each.
