Is the blue room in question solvable with 14<=girth<=16 and the walk/jump/bite/stick powerups, or do I need to look elsewhere to progress? To be direct, when trying to deduce the necessary steps for solving this puzzle with 14<=girth<=16 girth and only these powerups, the puzzle seems impossible.
That the old layout had to be changed to be three tiles high makes me strongly suspect what the intended solution is here, but with the constraints of a 2x3 body layout, I simply can't see how this is doable without the delete powerup. After scanning videos to determine where to get delete, this seems like the bottleneck I'm going to have to surmount, which creates an unsolvable problem (if I am correct).
I'm aware that I could be making some flawed assumptions that have lead to incorrect conclusions, but at this point I'd like to be told explicitly whether this is solvable with what I have. Discounting speedruns, which I don't want to watch because their times suggest they feature game-breaking exploits, every upload of this game I've found (I've scanned through every playthrough I could find) solves this room either by abusing girth or the teleportation room mechanic.
