Jalapeno

The Jalapeno is a high-damage explosive that can clear an entire lane of zombies, melt Zomboni's ice and melt Dr. Zomboss's ice balls.
Its shape and name are based on the chili pepper, valued for its spicy flavor.

The Jalapeno's name is misspelled in the game; the correct spelling is Jalapeño, and because of this, the Jalapeno should be pronounced Hal-A-Peen-O as opposed to the correct Hal-A-Peen-Yo.

Jalapeno's Right eye twitches

It seems that the Jalapeno is actually sweating. This may be due to that it is hot as it is a chili, or it may just be reflections from the sun. It may also be since he is nervous about the explosion and trying not to detonate at the same time.

The Jalapeno plant in real life is not actually the hottest chili pepper. In fact, the hottest pepper, the Trinidad Scorpion Butch T Pepper is the hottest, which is 1,463,700 on the Scoville scale!

The flaming effect is, assumably, due to the spiciness of a chili when eaten.
