Plants vs Zombies 2 - Special - Turncoat or Double Agent Zombie - December 2023

This is something we have never seen before - a turncoat zombie or a zombie which is a double agent.

Look at the Gargantuar on the bottom right of the screen, on Row 5. You see a poisoned giant zombie which will be hypnotized from Penny's Perk.

About one (1) second later, this Gargantuar is converted back, presumably when the Wizard or Healer zombie targets the giant undead guy.
