Super Mario World/Enemies/Jumpin' Pumpkin Plant

This plant is only found in SMW after you beat the special zone. The jumpin' piranha plants turn into jumpin' pumpkin plants. They act exactly the same, though their appearances are different. The piranha plants mouth faces upwards while the pumpkin plants mouth faces towards the screen. (This doesn't mean you can jump on top of them now. You will still get hurt.)
