These are just ideas, not an actual game. These are potential enemy ideas for https://scratch.mit.edu/projects/1305153836 by @bbeans519 that might get added. @bbeans519 might add some to his game; if he does, then he will remake the costumes, so they may look different in his version. He may also change some of the mechanics.
Crab- moves around the bottom of the screen while reaching its arms out towards the top of the screen. Seahorse- moves towards the player, while camouflaging with the background. Sea Urchin- spawns baby sea urchins that float to the bottom of the screen. Pufferfish- goes around the edge of the screen while shooting spikes towards the player. Whale/Bloop- gives the player a warning before it attacks; goes from one side of the screen to the other while devouring everything in its path. Clam/Oyster- goes from one side of the screen to the other; bites anything it can get its mouth on. Marlin/Narwhal- goes directly to the player; warns the player when it is going to attack by making an angry expression Penguin- goes from a top corner to a bottom corner really fast while trying to eat the player. Trash/Pollution- goes from one side of the screen; when the player touches it, the shrimp gets stuck to it.
