Goopy Le Grande Is The Second Boss In Cuphead, He Has Three Phases, His first being a bouncing blue ball that bounces around, he has one attack which he leans his head at you, duck under it to not lose any health, His second phase is a bigger goop that has one attack which is a boxing punch, duck under it to not lose any health, His third phase is A grave that runs around and eventually slams himself on you, I use the smoke bomb charm for this but you can just dash through it.
Yo Did You beat Goopy Le Grande?
Yes He was mad easy
