His fight . Nail swing-swings his nail doing 1 mask of damage.

block and counter

bobbi bill will do a hide animation kinda like turtle and he's blocking or countering so he might just be blocking and he blocks your attack or he ready to counter and doing 1 mask of damage on hit but for both you can't do damage to him with your nail

shield bounce
charges then runs back and forth and sometimes jumping on hit dealing 1 mask of damage and when pogoed on his back while he is in the air it will flip him allow you to damage him (P.S he still rolls back and forth but doesn't jump.
