A nerdy blue anteater who is one of the most intelligent characters in the series. He is the second character without a heart nose and a pair of buckteeth. He usually likes doing and reading science and math problems. To reinforce the 'nerd' image that Sniffles exudes, he is seen dressed up as a Star Trek character (probably Spock, the Vulcan ears being the giveaway) in Remains to be Seen and Something Fishy along with Mime , and also sports a pocket protector on his chest.
Sniffles' IQ has proved to be extremely high in both the internet and TV series. He has built things that are far more advanced than most of the other characters (ex. a rocket from a school bus and even a time machine). Sometimes, however, these devices can malfunction and work against him, leading to his own death and the deaths of others. Like Toothy, he has a wide range of deaths, usually involving either his tongue, his head, his limbs, or his organs. He also has a multitude of jobs, including a doctor and a pilot. In addition, he is sort of a mad scientist (as shown in his Smoochie) mixing fluids which causes his death. He usually says "Ah Ha!" for when he gets an idea for an invention. Sometimes, he gets angry with Lumpy or Cuddles such as Wingin' It, In a Jam and Tongue in Cheek.
Sniffles also has a craving for ants, which is one of his animal instincts. However, whenever he tries to eat one, they kill him after torturing him in the most sadistic manners. Only in the episode Blast from the Past has Sniffles eaten an ant without being killed. In general, Sniffles' deaths are slower and more painful than most of the other characters. Tongue in Cheek had to be his worst and longest death, bringing him to tears from the extreme pain or sheer despair. On some occasions, especially in newer episodes, he dies quick deaths, similar to Mime; who has instant deaths.. Similar to Cub, Sniffles rarely survives in the episodes he appears in. The only episodes that he survived are Happy Trails pt. 1, Stealing the Spotlight (debatable), Blast from the Past (with the time machine), See What Develops, Wipe Out, Easy Comb, Easy Go, Hear Today, Gone Tomorrow, We're Scrooged!, Happy New Year, Happy Tree Friends: False Alarm episode, Youtube Copyright School, Spare Tire, Camp Pokeneyeout and Dream Job.
His mouth and nose are combined to make a trunk-like snout, with his lips at the tip. It used to be long in the Internet shorts, but starting with the TV series, it became much shorter. The reason for this was to add additional cuteness to his appearance.
It is worth noting that Sniffles, although not one of the four center characters (Lumpy, Cuddles, Giggles, Toothy), is beginning to become more of a main character. He has the second most starring roles in the TV series at a total of 6 starring roles next to Lumpy, who has 16. He has also had a total of 17 starring roles if you add up his starring roles in TV and Internet episodes.
In the "Collect Them All section", Sniffles has a few allergies and he loves calculating long division problems.
He has a MySpace account that shows that his idols are Albert Einstein, Spock, William Shatner and Splendid. Sniffles is the second character to idolize Splendid (along with Toothy), further evidenced in Suck it Up and A Sight for Sore Eyes. He is best friends with Nutty as seen in From Hero to Eternity and Random Acts of Silence. He is also friends with Giggles as seen in Boo Do You Think You Are?, Happy Trails Pt. 2: Jumping the Shark, I've Got You Under My Skin, Every Litter Bit Hurts and Idol Curiosity. He has also been in a few episodes with Lumpy in In a Jam, I've Got You Under My Skin, See What Develops, Take a Hike, From A to Zoo, Class Act, A Hole Lotta Love and Blast from the Past.

- Sniffles is the first character to have an episode where he starred without any other main characters in it (Crazy Antics).

- He started the rivalry between ants and anteaters in Blast from the Past by eating a prehistoric ant in front of a prehistoric anteater.
- It is possible that Sniffles wears a shirt since he is seen with a pocket protector.
- He may have been based off of the aardvark from the Pink Panther show. Both are colored blue, usually fail to catch ants, and tend to get injured quite a lot. Unlike the aardvark, however, Sniffles is extremely intelligent.

- His ear shape is unique.

- He is one of only two male characters (the other being Cub) with a female voice actor.
- Early on in the series Sniffles' snout was long but during the TV series, Suck it Up his snout became shorter. This was made to add cuteness to his appearance.
- In Internet Season 4, his snout becomes more straight instead of curved.
- He has a lot of money as shown in the episode We're Scrooged!, possibly because his intelligence allows him to have high-paying jobs.
- Flippy has always killed Sniffles and Nutty in the same episode.

- He has the second most starring roles in the TV episodes, the most being Lumpy.
- He is the most frequent victim of The Ants and debatably the only victim of Mittens/Honey .
- He is the only major character to be an animal not from North America (anteaters are from Central and South America).
- Like real anteaters, Sniffles has very poor eyesight. Though he wears glasses to help himself see.
- So far the only starring roles he has survived in are Blast from the Past (only with the time machine in an endless loop) and Dream Job (only suffering a minor hallucination episode despite all the dream deaths).

- He has starred in 6 TV episodes, in 3 of them he killed other characters, and in the other three, he didn't..

- Sniffles and Mole are the only characters that regularly wear glasses.
