Killer whales are the third biggest creature in the game, only passed out by Goliath the great white shark at full size and the Alien Intruder at full size. They appear in 8 levels in the game, or 2/15 in total.
They appear in Goliath and Layla levels, but only eatable by Goliath. Layla's huge form is just one level smaller than an orca.They eat pompano, cuttlefish,leopard sharks, marlins,tuna, pufferfish, john dorys, barracuda and herring. They are driven out by the Intruder but manage to come back with their last level being Tricky Treats before they're driven out once again.
It is based of Kotal Kahn from Mortal Kombat X.
