The Dinosaur Stampede ambush every wave will ruin any defense if not countered. Luckily, the player is given Dinonip, which will counter this (with Plant Food). In addition, the Power Lily is also given to supply much Plant Food to counter this. For the level itself, the Dinonips should easily take care of the zombies. However, in hard mode, it is virtually impossible without a leveled up Dinonip (preferably to Level 4). Although, it does take a while to get Dinosaur Grass up to Level 4, so do not expect to beat the hard mode in a while.
Gosh, I can grow leaves!
