Thorn-pult

The Thorn-pult is the Cesspit/Weed version of the Cabbage-pult, except slightly more powerful and can pop balloons and tires. Other from that, it's pretty much a normal Cabbage-pult.

These work better than Cabbage-Pults in normal levels, if you can afford the extra sun.

Almanac Entry
Thorn-pult flings bundles of vines at zombies.

When Thorn-pult was just 5, he went exploring. He went deep into the forest, and got tangled up in some vines. Ever since, he's hated them and flung them away as fast as he could.
