Hammer pea

Two on the left, two on the right, and a side of WHACKAMAPOW!

Info
This plant is supposed to be an upgrade to split pea(due to similar attack pattern). He spits 2 peas on both sides... Good. But the main factor here is his melee attack used to defend himself. He doesn't pound zombies as fast as he shoots, but he does a whopping 160 damage to zombies(every basic zombie has 200 hp, so he could insta-kill an imp)!

Since he appears in the second adventure, he's quite hard to get. But it's definitely worth the effort, with the upgrading process.

Strategies
Like split pea, he's best used near the middle of the lawn. Since he's the only upgrade plant(so far) to take 10 seconds to recharge, you can upgrade your split peas with ease! He's effective against miners and other "go behind your plants" zombies.

Almanac entry
Hammer pea

Sun cost: 175

Recharge: average

Shoots 2 peas from both sides, and hammers them when they get too close.

Special: hammers zombies at close range.

He was made fun of his unusually shaped head, which looked like a sledgehammer with two holes! However, after showing what he was made of and hammering zombies, he was still made fun of. Not the plants this time, the zombies.

PvZ2
He re-appears in PvZ2, where he retains his role as a hybrid plant. He now costs 300 sun here, which references the total cost of placing a split pea and upgrading it to this plant.

The strategies are the same as before, but his hammer now inflicts knockback, letting him defend himself for a bit longer.

Since he can't hammer flying zombies, he can still blast them in the back! Prospecter zombies will get blasted by his back cannon, and imps will still get crushed to their doom.

His plant food ability is a combo of split pea, repeater, and bonk-Choy. This isn't really necessary on easy levels, but at level 5, he can take down a gargantuar with it(Which is why you need a lot of seed packets to upgrade him)

When costumed(in Chinese version), he will start spitting 2 rocks both ways instead of 2 peas. This does 30 per rock, so it does 60 damage in total.

PvZ1 specific

 * His hammer ability is slower than chomper's bite. Way slower.

PvZ2 specific

 * This plant is one of few plants to be put in an extension of an already existing world, being the far future's veteran levels.
 * His almanac joke is a reference to skywarp's prank of pushing people down stairs. In fact, since his hammer does knockback damage here, he can actually push zombies off of ships and into the water below! We need no plank matey!
