new Idea... even if you made it to your max limit of 24 why not add a tier 4 or an even more bigger size to the point rolling is your only option even if breaking your maximum stomach capacity limits 2 or 3 times but sadly a new item in store for purchase would be called "honey pot helpers" which can help roll you around and store honey as you move or another movement option in the store "boulder roll" which allows you to have the ability to roll all on your own but your deeply squishing yourself against the floor and have an even harder time trying to get around without getting dizzy so moving too much would invert your controls but you can expand as huge as possible without becoming completely immobile by your helpers which have a strength limit which only depends on how big and heavy your size is.
sorry about the idea mess... my mind keeps on spilling out even more ideas each time i come up with something whatever comes out from inside my head.
