Essentially the enemy counterpart of Zamboney Cat, Kid Tappa is a very speedy enemy with a 15,000 HP barrier, one knockback and a great deal of health, especially if the player doesn't have all Anti-Starred Alien Treasures. This combined with his short range of 100 makes him quite effective at his role: protecting other, stronger enemies. However, Kid Tappa's attack power and overall DPS is extremely low, making him a setup fodder. So if he's by himself, he won't be a threat.
Barrier Breakers such as Loincloth Cat or Fencer Cat can obliterate the shield, although they aren't necessary to bring if you have cats with attack power over 15,000. All that's required after is damage, so bring strong attackers such as Seafarer Cat and Can Can Cat or any Uber Rare Cats to destroy the dolphin as soon as possible.
