User blog comment:A Graalian/Who would you rate the hardest Zombie in PvZ2 and OP plant in PvZ2?/@comment-5792287-20150407110346

Zombie: Surfers. I would say Wizards, but they are normally only a big threat when in massive numbers. Surfers on the other hand are a massive pain in small numbers, and a true MONSTER in large numbers.

Plant: If counting combos, then Spring Blovers.

Otherwise, Fume-shroom because of the glitch in the latest update.
