Ever since the disappearance of Looey and Blot.. there's been subtle differences in yattas behavior

She's always been energetic, hyperactive and outgoing and comes off a little weird but recently she's been more hyperactive and jittery, she's probably trying to outrun her sadness physically, constantly moving, performing acrobatics, or crawling through the vents (one of her known habits) to avoid confronting her emotions head-on.

Unlike other toons besides certain toons you could read others like an open book with amazing handwriting and for this problem you knew something was up with her. You took notes of her actions recently, planning to show them to dandy so he can try to help others understand Yatta better.. well not like his dumbass would do anything but go "oh that's odd".

Yatta has an intense obsession with candy and stores it everywhere, including in the vents. She's starting to consume candy even more excessively

Well eventually you see Yatta in the kitchen she's climbing on the fridge while her tail is softly swaying and sprout is looking at her strangely but is keeping to himself while baking sweets. Yatta turned to him and started speaking

"OOO..are those..SWEETS??"

She sounded excited.. probably drowning herself in candy to distract herself

"Yup..there cookies"

Sprout said happily, he probably didn't even know why Yatta was extra hyperactive

"GIMME GIMME GIMME!"

Yatta exclaimed while shoving them in her mouth as Sprout sighed

She noticed you she held out a cookie while being on top of the fridge like some gremlin

"HEY..YOU! COOKIEEE!"

She exclaimed while she was reaching out to you..also while about to fall off the fridge

You always wondered why Yatta loved sugar so much it kinda concerned you
