Chilly Pepper's name is a portmanteau of the chili pepper, a species of pepper, and the homophone "chilly", meaning cold.
He looks cold, but maybe he's hiding an explosive temper. Or, he could just be really cold.
There is not much a difference between Jalapeño other than the larger cost and expensiveness of coins. The Chilly Pepper is implemented to take care of Gas Can Zombie. But because a Snow Pea can do so multiple times, and it is cheaper, so it is much more advised to use one. The Chilly Pepper can however, be used as a third instant kill if you want to have Cherry Bomb, Jalapeño, and himself in one level for a faster use of instant-use plants to stall down time. It is possible to use a Chilly Pepper, instead of Jalapeño to damage and temporally freeze Gargantuar Zombies, although it is recommended to time the activation so that the Gargantuar Zombie is not frozen where he is barely hit by anything. Do not use the Chilly Pepper against Ice Block Zombies, as they are totally immune to the explosion while they are still in their ice block.
