Hoppy Hopscotch is an energetic and enthusiastic rabbit, which is represented by her lightning bolt pendant. She is particularly fond of outdoor sports, specifically soccer as shown in the Intro to the Smiling Critters Cartoon. Like the other Smiling Critters, Hoppy Hopscotch showcased an unnerving and maniacal personality when CatNap came to DogDay's house during her sleepover. Her retained excitability was shown when she chanted, "Sleep! Sleep! Sleep" to CatNap, encouraging him to use his abilities to overcome her fear-induced insomnia. When CatNap complied, Hoppy Hopscotch showed signs of insanity, addiction, and mania when inhaling the sleeping Poppy Gas, laughing hysterically with the others until she passed out.
