Yeah; it appears that newer zombies (especially Zombie Kings, Wizards, and the BWB Part 2 zombies) are always dangerous, from what I have seen and heard. Even the toughest things Pyramid of Doom, Dead Man's Booty, and Big Bad Butte can throw at the player are fairly easy to counter if you're prepared; PoD's main threat are Explorers, which can be countered with Spikeweed/Spikerock easily, or Winter Melons for a more permanent solution; DMB has Imp Cannons and Seagull Zombies as its most threatening ones (Pirate Captains aren't too tough); Far Future made them mostly painless with the Laser Bean. BBB has Prospectors and Wranglers; Winter Melon is optimal for both due to its sheer melonocity and freezocity; Wranglers are most effectively defeated with Spikerocks, and early on, Prospectors can be taken care of with a column or two of Split Peas.

TfT is a bit more of a challenge, with a more deadly Gargantuar and the eternal threat of Football Mechs, but still, you're supplied with an effective anti-machine counter.

AC and TT? Its strongest zombies get harder as time goes on instead of easier.
