No matter your Level, the chomper's HP and stats are atrocious and it's more than liable to get KO'd in a single hit of anything . But if you must know, its special attack is Venomous Chomp, which causes damage and potentially poison.
After defeating the chomper and perhaps feeling a tad sorry for it, you'll earn 10,000 pg by default. Which isn't quite a "million", but for those near the beginning of the game, it's close!
