The first question I'm actually hoping a response for, since I'm interested in making a Willump costume and want to see if I'd be suited for it, or stick with Nunu instead!
For the first question - you won't be suited for willump belive me. He is quite big as seen on the splash. You can always cosplay him tho. It is not neccessary to be scale 1:1. It will proabably be 1:2 or 1:3 but still.
Nunu is presumably about 8 years old. Based on the size of an average kid of that age he's probably around 4'2. Based on model size, Willump is about twice as tall as Nunu (so ~8'4-8'5); this is basically the size of a huge fursuit on a tall guy with stilts. Willump is a pretty easygoing yeti so he probably would be fine with human food. Especially meat.
EDIT: Based off splash, let's just say Willump is like, TWICE my previous estimate. Big boi.
