Jurassic Marsh - Day 20 is the twentieth level of Jurassic Marsh in the Chinese version of Plants vs. Zombies 2. The Ankylosaurus and Egg Stealer Imp make their first appearances in this level. After completing this level, the player receives a money bag.
This level introduces a lot of new content, which the player may not expect immediately. Firstly, the Ankylosaurus is a dangerous dinosaur. It acts like a stationary Mecha-Football Zombie, except it can push groups of zombies. The Egg Stealer Imp is also present in this level. The Egg Stealer Imp quickly carries an Egg across the lawn until defeated. This can be very detrimental to defenses if not disposed of immediately. Lastly, a new baby dinosaur is introduced, the Baby T-Rex. This is perhaps the most dangerous baby, as it will summon a Dinosaur Stampede. Suggest bringing Dinosaur Roar Grass to counter this.
