Multiple Nuts:

So basically there is an OOB glitch that is currently useless in the Any% route. It takes you to the Sandy karate fight and then the treedome, but is useless as the acorn to get upstairs is inaccessible. As it is possible from the beginning of the game, it is a much shorter category for those who don't want to live out the 2 and a bit hours it takes for Any%. This category gives the OOB a use.

Nut Jar:

This category is similar to Any% up to Treedome. It ends before the arguably worst segment of the game, Jellyfish Fields. Nut Jar removes the need to grind for Jellyfish and is good for practice.
