Ice trail
An Ice trail is an environment modifier left behind by a Zomboni which makes the player be unable to plant any plants on it. It will disappear after 30 seconds or if the player uses Jalapeno to melt it. Wherever the ice trail appears, a Zombie Bobsled Team may appear on it, with the exceptions of Level 5-10, Dr. Zomboss's Revenge, Invisi-ghoul, Heat Wave and Survival Mode levels.
Ice trails return in the Plants vs. Zombies 2, and are also created by Walrus Zombies in Chinese version of Plants vs. Zombies 2.
In Plants vs. Zombies: Great Wall Edition, ice trails are replaced with Pavement trails, which still function identically and can still be destroyed by Jalapeno.
Plants vs. Zombies 2
In the Plants vs. Zombies 2, ice trail is also known as slippery ice, once again, left behind by a Zomboni. It absorbs 200 damage, and can only be unfreezed or damaged by certain plants. It will disappear after 45 seconds and spawn Zombie Bobsled Team every 13 seconds.

Strategies
- See Zomboni and Walrus Zombie for more strategies.
Ice trails can be very tedious if the player does not kill the Zomboni or Walrus Zombie quickly, as they do not allow the player to plant on them, and causes the Zombie Bobsled Teams and Ski Zombies to appear to rush ahead. However, the player can destroy the ice trail using a Jalapeno to melt it. The other method is to use some strong plants such as instant kills to kill the Zomboni or Walrus Zombie before it leaves too long of an ice trail. The player can end the Ice Trail quickly by using a Spikeweed on the Zomboni or by using a Whirlwind Acorn on the Walrus Zombie. If the player doesn't plant it on time, they can use a Jalapeno to kill the Zombie Bobsled Team or Ski Zombie and the trail at the same time.
Be sure to destroy the Zomboni quickly to prevent the trail from getting dangerous. The longer the trail is, the harder it will be to defend the lane due to being unable to plant Spike-weeds to prevent other Zombonis from making the trail last longer.
