Spike Crate

Spike crates are a type of crate that only appear in Crash: Mind Over Mutant. They are gray crates that have a sinister looking smiling face on the front. When Crash approaches, they spout spikes and start spinning, when they stop spinning they can be broken open for crates.

Trivia
Spike Crates bare a striking resemblance to the Mario Serie's 'Thwomp'.
