ToToiToy is first seen playing with his dump truck in Episode 2 when he got fascinated with BoBoiBoy practicing his powers next door. He said that BoBoiBoy Lightning's Lightning Sword was 'pretty'.
He makes a brief appearance along with Yaya and BoBoiBoy Wind in Episode 11, who are making biscuits for World Biscuits Day. He ran away when Wind ate her biscuits which contained Chemical X and prompted his transformation into BoBoiBoy Cyclone.
Being a young baby, ToToiToy is easily amused by things and just likes to have fun. Although, like all the other people in the universe, he detests Yaya's cookies, fearing them.
- His name is identical in structure to BoBoiBoy's name. It's possible that this naming structure is common in the BoBoiBoy Universe.
- Although it's unknown why Potato is no longer Yaya's pet, it's possible that ToToiToy's arrival caused Potato to be displaced, but it's more likely that Potato merely ran away.
- In Papa Pipi, he is now a preschooler and he is known by his real name "Otoi".
