PVZ Starstorm!: Fill the whole lawn with Starfruits in Seeing Stars (idea got from PK Starstorm)

Dance Party: Put 5 Dancing Zombies all at once in any I, Zombie level (or in an I, Zombie Endless streak), then keep them alive to allow them to eat all the brains.

The Ghoulympic Games: Put out at least 2 Pole Vaulting Zombies, 2 Football Zombies, 2 Snorkel Zombies, 2 Zombie Bobsled Teams (only when there's already an ice trail), 2 Baseball Zombies (modded normal Zombies) and 2 Catapult Baseball Zombies (modded Catapult Zombies) in a hacked I, Zombie level that has a pool.

All At Once: In any levels with columns of zombies, kill all the zombies in 1 column all at once (any plants will be OK, except for Spikeweed, Spikerock and Instant Kills)
