A Grouper is an orange Crasher. It spawns in groups of four in the pentagon nest.
The Grouper looks like an orange irregular heptagon.
A very weak crusher comes in a number of four and spawns commonly in the Pentagon Nest. It is very fast.
Don't stay close to a rammer if this crasher is nearby. This crasher can help it ram you. But alone if not on very low health, they don't pose a threat. Be wary of this crasher, though because it can do quite a lot of damage to glass builds, and a Destroyer (crasher) can come and one-shot you after this, and yes, this happens quite commonly through crasher related deaths. And avoid it when at low health because on rare occasions the fourth grouper kills you.
- The Grouper is the only crasher that spawns in groups.
