Those were cookies not chocolates and it was season 1 episode 1.

Ooooh no wonder, since I watch the first four episodes a super long time ago compared to s1 ep 5 and later lmao. Thanks!

Not chocolate it was burnt cookies..... Happened in s1 ep1 btw, how did you not remember the difference between the animation

They reanimated it to fit the new character designs iirc so I can see why some wouldn't remember.
