I Noticed there are a few areas where the overworld doesn't recognize I'm fat and let's me jump around normally. I can't seem to figure out what exactly is causing it. It has happened twice thus far. First in the Emerald Dragon palace. I assumed that it was when I was fat and tried using a trap to inflate. I was still fat and I noticed on another floor the jump button wasn't right. Now I'm in the Candy Factory and I think this was due to fattening through battle, but again didn't notice when it happened, just that it did.
Second part is as pictured. I noticed while jumping around this way (it's faster if I don't have the Chubby Chaser equipped) I am able to go over walls. I don't think it is all of them, but there are a few like this one, where I can't walk through, but am able to jump through. I first noticed in the factory room jumping back after getting the helium tube for Gally. While jumping back, I was able to jump directly onto the catwalks without having to go all the way to the stairs.
Tried to be as detailed as possible. Hope this helps
