Giggles is a pink chipmunk who has a light-pink diamond-shaped marking, a light-pink oval tummy, and a big red bow on her head. She has the personality of a young girl, as she enjoys frolicking through flowers, having tea parties with friends, ice skating, and having a shy and sweet demeanor. She has a romantic relationship with Cuddles, as well as being best friends with Petunia.
- She is one of the few canon characters to date other main characters (probably because early on in the show show that her, Petunia, Flaky and Lammy were girls characters that existed on the show).
- In the canon episodes, prior to the airing of the TV show, and Petunia had nearly identical personalities.
- In the canon episodes, she has been portrayed by several voice different actresses.
- Most people mistake her for a bear, as the creators never gave her a tail.
- According to Kenn Navarro,he confirmed that Giggles does have a tail, it's just so short, we can't see it.
- The First Blood DVD reveals that Giggles enjoys crossword puzzles.
- Giggles tends to get splattered by the blood of other characters much to her disgust or shock. This can be seen in This Is Your Knife, Every Litter Bit Hurts, I've Got You Under My Skin, and We're Scrooged!.
- Coincidentally, all of the characters whose blood has been splattered on Giggles are the same characters who she appears with in Blast from the Past.
- Giggles and Petunia are waitresses at the Happy Tree Cafe. Giggles is seen working there in Concrete Solution and Petunia is seen working there in A Change of Heart.
- In Crazy Disco, Giggles and Cuddles are seen wearing bikinis (even though Cuddles is a boy). In the updated version, Disco Inferno, they do not wear bikinis. This was done by Cartoon Star and not Mondo.
- She is the character who gets paired up with male characters the most.
- Giggles is also the character mainly used for Valentine episodes and love themes; she has been seen with Cuddles, The Mole, Russell, Cro-Marmot, Mime, Flippy, and sometimes Splendid.
- This makes her infamously unpopular with some of the fans as they see this as her cheating on every guy she's ever dated.
- She is also infamous for dating Flippy, which made a lot of fans furious since Flippy is rather more commonly shipped with Flaky.
- In her Season 1 pop up and Spin Fun Knowin Ya, she doesn't have her head markings.
- Giggles and Petunia both dislike Disco Bear big time.
