Second worst boss ever. The worst boss is Zombot Multi-stage Masher, because it's not even a Zombot, and also, 1 STAGE ONLY, not Multi-stage... The Zombot Dinotronic Mechasaur is not much different from the other Zombots, just calling zombies, shooting missiles and destroying all plants and zombies in two lanes... And it just based on the old-time dinosaur, that's too old... Well, that's maybe Popcap's only choice, since the ONLY THING that's new here is the dinosaurs... JM is such a boring episodes (Seriously, there is a volcano near there, so why they don't just let it explodes to create a surprise attack?!!!) Also, the boss is always Dr. Zomboss?! Lame... Why they don't make a new enemy + a BRAND NEW Zombot? In the animated films, there is not just one enemy in all episodes... For example, Wander Over Yonder, the enemy is not always Lord Hater.
