Much like Template:PvZHLink and Cosmic Yeti, he is based on a Yeti, albeit one from prehistoric times. He may also be based on the Sasquatch, more commonly known as Bigfoot.
Description change: Was originally His lunchbox is just a solid block. He hasn't invented "opening things" yet.
Strategies
With
Alone, he has below average stats for his cost. However, his Evolution ability can quickly turn the tide in your favor, essentially making a 4/4 zombie, then playing a Template:PvZHLink. Of course, you need a zombie for Evolution, so be sure to pack some disposable zombies.
Because of his pet tribe, The Smash can use this in a pet deck with Cat Lady and Zookeeper, and he will be a huge help due to pet decks being swarm decks. The only issue would be to hold out until turn 5 without any negative consequences, which can be hard for a pet deck.
Against
If played without Evolution, this is not particularly threatening. You can use tricks like Template:PvZHLink, or plants with 4 or more, like Template:PvZHLink, to take it out. The real problem comes when it is played on another zombie. However, Template:PvZHLink can destroy all the boosted zombies fairly easily. If you don't have Doom-Shroom, then resort to tricks like Template:PvZHLink to take out the boosted zombies one by one.

Trivia
Ironically, Primeval Yeti opens his lunchbox to activate his ability, completely disproving his old card description.
