Chill Out

Difficulty: Medium-Hard

Strategy 1
The best level to do this on is probably Level 3-10 as a lot of Zombonis appear, and therefore Zombie Bobsled Teams appear, and Jalapenos come on the Conveyor Belt quite frequently. Just make sure your lawn is not to overloaded with plants.

Strategy 2
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. You can only using Jalapeno and Imitater Jalapeno and then keep surviving until the Jalapeno is ready, kill another Zombie Bobsled Team then restart the game, and you still get the achievement.

Strategy 3
Pick up level 3-10. This strategy is quite simple.Just do not plant Spikeweeds. Save them for "critical" Zombonis. Leave the ice trails. It is very good if you have at least 2 Jalapenos in the back. If the ice trails are long, there will be a chance of two bobsleds coming one behind another. Then use a Jalapeno. When anoher Zombie Bobsled Team comes, use a second Jalapeno. Voila! You got this achievement!

Trivia

 * You must encounter the Zomboni to obtain this, except in Bobsled Bonanza.
 * The description of the achievement is a pun on the words said by the Jamaican team in the movie Cool Runnings: "Feel the rhythm, feel the rhyme, get on up, it's bobsled time!".
