Jurassic Marsh - Day 20 is the twentieth level of Jurassic Marsh in Plants vs. Zombies 2. It requires the player to produce at least 2000 sun. When this level is finished for the first time, the player unlocks La Brainsa Tarpits, the Endless Zone of Jurassic Marsh.
The objective to produce at least 2000 sun is relatively easy, especially with two flags in this level. So, the player should not focus on sun production that much. Two rows of any sun-producing plants will do. Dinosaurs do not pose much threats in this level, and the first wave does not appear as quickly as other levels in this world normally happens earlier. However, that does not mean that they will come slowly enough for the player to set up a proper defense, so he or she must be careful.
- The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.
