Ice trail

The Ice Trail only is left by Zomboni. You can't plant any plants on it. It will disappear after 30 minutes or you can Jalapeno to melt it. It is quite annoying because it can let Zombie Bobsled Team appears.

Strategy
See Zomboni for more strategies.

You only can use Jalapeno to melt it. Other method, you should use some strong plants such as Instant Kills to kill Zomboni before he leaves too long ice trail.

Trivia

 * Strangely, Ice Trail can't cover the daisies.
 * If a Zomboni appears on Roof levels, then he will stop laying an ice trail after it reaches the slanted portion of the roof.
 * Strangely, tiny Zombonis (encountered via hacking) can leave a full size ice trail.
