Cuddles is one of canon characters of Happy Tree Friends. He is the show's official mascot even though Shifty was created first.
Cuddles is a yellow rabbit with pink cheeks who inexplicably wears Pink Bunny Slippers. His white curly hair tuft and cotton tail look exactly the same. His ears sometimes move to match how he feels. For example, when he's happy/energized his ears stay up, and when he's upset/sad they'll drop down.
Cuddles' personality is somewhat mixed. On one hand, he can be dangerously mischievous and a fun lover. Both of these characteristics have led to the death of both himself and other characters (Flaky being usually who tries to warn him). On the other hand, he is usually lovable, optimistic, friendly, sweet and caring, making his personality more complex than the others. Cuddles' personality is also known for its innocence and naivety, which makes him easy to manipulate by other characters, an example of this is when Lifty and Shifty take advantage of him in Junk in the Trunk, or in In a Jam when The Mole makes him donate blood twice to get his new guitar. As revealed in In a Jam, he is referred to as a music lover, mainly rock music. He was seen to have multiple houses, but his official one is considered to be a hollow tree, as it is the only one to appear more than once (In a Jam and Hear Today, Gone Tomorrow). He is particularly good friends with Toothy, Flippy, Petunia, Flaky, and Lumpy. Cuddles and Giggles are also very close friends, and it has been hinted several times they are romantically involved. Their relationship is most prominent in the Fall Out Boy music video The Carpal Tunnel of Love, and hinted at in the internet episode I Nub You.
- He may like the color pink, as he has pink bunny slippers, has pink cheeks, and his girlfriend in a few episodes is Giggles (who has pink fur).
- The Collect Them All section of the First Blood DVD reveals that Cuddles has a Master's Degree in karate.
- Cuddles' appearance is similar to the Nickelodeon character Spongebob, since both are yellow, have pink-red cheeks and big teeth, they also have similar personality, since both are very happy and friendly and dedicated to what they like, apart from their innocence. They both are smiling most of the time.
- He also may resemble Pikachu from Pokémon. Back when the first episode of Happy Tree Friends premiered (late 1999), Pokémon was incredibly popular.
- Most of the time, Cuddles keeps his bunny slippers on, but in the episodes Happy Trails Pt. 1 and Home Is Where the Hurt Is, Cuddles' slippers are seen off of his feet after his deaths. There is even a goof in The Carpal Tunnel of Love where Cuddles' slippers are completely missing from his feet at one moment.
- According to the Pop Corn video version of Spin Fun Knowin' Ya in the First Blood DVD, Cuddles starred in the Ninja movie series "Paws of Fury". This is a parody of the Bruce Lee movie Fist of Fury, the joke being that Cuddles is a rabbit.
- Cuddles is the most advertised character of HTF in real life while in the show, Splendid is most advertised character.
- Cuddles' silhouette of his head has been used for the logo of Happy Tree Friends for certain brandings.
- In the HTFgames.com arcade game Crazy Disco, he is seen wearing a bikini, even though he is a male character. In the updated version of the game, Disco Inferno, he is only wearing his normal bunny slippers. This was done by Cartoon Star and not Mondo.
- Cuddles currently has the most deaths of any canon character in the series.
- Cuddles is similar to Kenny McCormick in South Park on Comedy Central as both die a lot.
