Stage 3-10

The zombies are finally ticked and invade with all the zombies in their arsenal! Be prepared...

 * Threepeater
 * Tangle Kelp
 * Jalapeño
 * Spikeweed
 * Torchwood
 * Tall-nut

Zombies

 * Zombie
 * Conehead Zombie
 * Buckethead Zombie
 * Their ducky tube variants
 * Snorkel Zombie
 * Zomboni
 * Dolphin Rider Zombie

Strategy
Plant Threepeaters as needed in the middle rows. Plant Torchwoods right near Tall-nuts, and Stack Tall-nuts in the Pool. Remember to place them in the second column from the right, or the Dolphin rider will not jump. Stack Spikeweeds on land, or if a Zomboni comes, use a Squash/Jalapeño. Snorkels should be taken care of quite easily.

Outcome

 * Sea-shroom
 * Stage 4-1
