Crazy dave has GROWABLE NUKES AND INFINITE SOLDIERS.

When one plant dies, a dozen are born, LITERALLY. seeds are fucking crazy, a single sunflower seed bearly landed in any grass and in SECONDS turned into a FULL GROWN PLANT READY TO KILL. if dave somehow dies it'll be the last thing zomboss does before GETTING NUKED A THOUSAND TIMES OVER.

Zomboss has AT BEST, 8 billion zombies, sure he can go through time and grab more but the gnomes gonna be on his ass. He can win battles, but he ain't winning the war. Every zombie blasted to bits, eaten burned beyond recognition, transformed into fungi, sent to the shadow realm, or SMITED BY RA THE SUN GOD is an UNRECOVERABLE CORPSE and he's gonna run out.

Machines are even WORSE. If the plants destroy his power grid, THAT'S IT. and nature LOVES taking her metal back so if starts rusting, UNRECOVERABLE. Hell, if dave goes crazy with making water plants, HE'LL HARD COUNTER THEM EVEN MORE. also em peach exists so yeah.
