Prior to the 7.4 update, Jurassic Marsh - Day 33 was the 39th day of Jurassic Marsh. It is a Special Delivery level, where the player must avoid having more than 15 plants. Upon completing the level, the player receives a Jurassic Marsh Piñata.
As of the 7.4 update, level expansions were removed from the world maps and placed into epic quests. Because of this, this level is no longer accessible from the map and must be accessed when the epic quest is available.
The main threats in this level are Jurassic Gargantuars and Jurassic Rockpunchers. Jurassic Gargantuar has very high health so that he dies after three explosions. Jurassic Rockpuncher dies after two explosions, making the tile where Explode-o-nut was planted useless. Plus, dinosaurs can support zombies to assault the lawn very quickly. The only plants the player can get from the conveyor belt are Explode-o-nuts and Banana Launchers. Luckily, those plants are offered in enough quantity, so the result of this game depends on the player's control using Banana Launchers. But be careful, as dinosaurs can quickly move the target, so the player should aim him correctly and swiftly.
- 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.
