Crustacean: A lobster heavily armoured with chitin and spawns barnacles periodically from its back. The pinch is immobilizingly painful. (6 Elixir, Legendary)
Burried Treasure: X marks the spot, nearby enemies greed get the better of them and will attack the ground until they find treasure! Unbeknownst to them 2 blinged out Guards are hiding inside that hop out into the fight! (3 Elixir, Epic)
Birds Nest: A pirate sees further with his telescope and tells nearby troops where the enemy is, thus increasing their range. (3 Elixir, Common)
Pelican: Swooping at a blazing speed with a bill full of fish, hits with such a force, the fish fly out and bounce up and down hitting enemies. (4 Elixir, Rare)
Fisherman: Casts his line out and snags enemies closer each hit. (3 Elixir, Legendary)
Flock of Seagulls: 7 Mighty seagulls swoop enemies down below. They can't swoop air enemies. (4 Elixir, Common)
Tsunami: This isn't just a tiny splash, a wall of water forms a crest and crushes down on enemies in the path. (6 Elixir, Epic)
Palm Tree: Frequently drops coconuts that fall on the ground. Coconuts, jump at friendly damaged troops breaking open to heal them, or spin their leaf to hurt nearby enemies. (5 Elixir, Rare)
