Slimetchi's sister. Chibiwatchi is a cheerful although childish Tamagotchi who enjoys parties. Unlike Slimetchi, she tolerates loud noises and bright lights. She is also shown to stay up quite late, often as late as 5 AM running on 3 hours of sleep.

She is also laid-back and is oblivious to others throwing insults at her. Did I tell you she has a fear of Pelicans?
