I don't know if were aloud to do a specie, so I did this:
Cactems Related families: Pokeys
Habitat: desert
Color: Cactem/Bud Cactem: green
Bald Cactem: Dark blue green
Cactem Caesar: Green
They love to camoflage within other cactuses and attck their prey when they come too close. Cactems are usually alone or with one other Cactem.
Cactem The normal Cactem, You can easily take them out by throwing a koopa shell at them. They can't move from their emplacement, so there easy to kill off. If you get close they'll try to jab you with their hands.
Bud Cactem A Cactem with a pink flower. They start attacking you earlier by throwing spikes from their bud. The spikes don't go a long distance, but still hurt you.
Bald Cactem The rarest Cactem. They're always alone, and dangerous. They poison you if you touch them. They have the same attacks as a regular Cactem but they can jump vertically.
Cactem Caesar The boss of Cactems. He'll try to Jab you with his hands, so smack them with shells, he'll lose them when they're touched. When he doesn't have hands, he try to smack you like a bat, so hit his crown with a shell to damage him. He'll grow back his hands and be a bit faster. Repeat and your done with him.
