Impulse regressing around zits crew head canons!
He's cheery and giggly as a little, very easily entertained by his friend's antics. He's also entertained by his own mischief, which doubles while small. There's nothing like seeing his friends react to his pranks or silliness.
Zits love how silly he can get, even if sometimes it means him spooking them or making messes. Sometimes during a good day, they can get him to tire himself out on giggles and make naptime easy.
This is good bc his overworker tendencies as an adult transfer over as a very restless and curious kiddo who Hates being told to stop what he's doing unless the new thing is equally or more interesting.
He's also extra sensitive. Poor baby cries easily. He's not big on cuddles unless it's with a stuffie or blankets, but he likes being picked up, even though big Impulse gets embarrassed by it. Lil Impy NEEDS positive reinforcement and delights over making people happy and helping, so naturally if someone gets upset with him, his whole day is ruined.
Grumpy baby Impulse comes about from: too much teasing, not enough sleep, things not working how he wants them to, etc.
Skizz and Tango are his "uncles". Zed isn't exactly opposed to the term for himself, but it does make him feel old. Skizz is actually fairly paternal about it, he can get protective over lil Impy- which Tango thinks is funny and endearing- but he IS still a best friend and as such is obligated to tease the little guy, albeit in a gentler way.
Joker (from jits streams) eventually is let in on it and he's more of an older sibling figure who is constantly encouraging Impulse's mischief. There's a bit going on where Joker also gets put in time out for things despite not being regressed himself, which everyone gets a laugh out of, and it keeps Impulse from always listening to his bad influence.
I'm gonna be giggling about Joker being put in time out for ages. I can imagine him protesting, all indignant, and Impulse giggling hysterically when Tango and Skizz add 5 more minutes to his time out for backtalk.
