Crates are a destroyable item that appears in de Blob 2. They can carry many things, like color atoms, inspiration, styles, galleries and paintbots. You can either charge a crate (press Z and B) but also smash it if the crate is not spiked on top. If you get rid of all the crates in a level, you'll earn the "Clean Up" Award. Smashing crates can be a goal of a challenge sometimes.
