Triplet Dogs

Triplet Dogs were a special-unique zombie in Penny's Pursuit in Plants vs. Zombies 2. They will appear on three at once. If one of them died, the other ones were died instantly. Also, they were immune to fire sources.

If you pay attention to their appearances, there was a white flash that moves around their bodies. It will switch from the middle to sideways of their bodies. The player must defeat one of them with the main spirit. If one of them defeated but doesn't have the spirit inside, they will switching lanes occasionally and their eating speed was two times faster than their usual speed. If one of them was defeated and have the spirit inside of it, the other one will die immeditally.

Origins
