Split in two pieces:
Stretch your body until it is larger than the level. Let your head and end hang down over the sides of the level while continuing to stretch. Eventually part of your body will fall off the level and respawn, and you will now be in two pieces. Put some distance between both parts and find the end section. Move your head near the end section and eat it. You can eat the entire section and your body will grow back out.
