Chill Out

The best level to do this on is probably Level 3-10 as a lot of Zombonis (and therefore Zombie Bobsled Teams) appear, and Jalapenos come on the Conveyor Belt quite frequently.

Another good level would be the Bobsled Bonanza Mini-game, due to the sheer amount of Zombie Bobsled Teams that appear; but using it to get the achievement could be difficult as not all strategies work well with Jalapenos.
