Bigfoot Zombie

The zombie yeti appears in the Hill area level ?-4. Just after crazy dave states he heard some strange noises in the forest. He is very tough. He is immune to freezing and slowing, because his long hair protects him. However, you can shave it using the Chainsaw Pea and make him vulnerable.

Suburban almanac entry
After creating the zombie yeti, Dr. zomboss said: "I know! I'll make a hairy bigfoot zombie!" After many hours of hair transplant, Dr. zomboss felt he was done, and he let bigfoot zombie go. Bigfoot ran into the forest and got lost in the shadows. He found a nice place to hide, and now he lives there. Bigfoot likes peace, so if anyone goes camping near his home, there's no doubt he will eat their brains. He and zombie yeti are best friends, they always chat via facebook. The distance doesn't separate them.

Strategy
You better plant a chainsaw pea to shave him, or otherwise he will have as much health as a gargantuar, plus he can't be paralyzed or slowed. Once it's shaved, it should be as easy to kill as a conehead zombie. As chainsaw pea are quite expensive, you'll have to save sun. You can also kill it with 2 instant kills, So a Summer Squash will be enough to take him out. However, the summer squash takes time to refill, and the bigfoot zombies commonly appear in groups of two. You can use a Doomy-o-Plant to kill them both, but it would be a waste of sun as the doomy o plant costs... 3975 sun! As you can see, it's way better to shave him first, as a repeater can easily kill them both (remember that the chainsaw pea goes trough the entire lane giving 8 normal damage shots to other zombies in it's way)
