Crate

A crate is an obstacle which isn't that hard to destroy when thinking about it most of the time.

Sometimes, they will have one or two woodplanks on them. It takes 2 times to destroy if there is one plank and 3 if there is two. This also applies with boosters. They can be broken with anything, including normal blocks, however, some of these crates will be colors, which can only be broken if there is a matching block's color to the crate's color. Boosters will destroy the crate no matter what in this case.
