Giga-gargantuar

The Giga-gargantuar is the second strongest zombie in Plants vs. Zombies (only Dr. Zomboss is stronger). It is a Gargantuar with red eyes that is only seen in Survival: Endless, Survival: Day (Endless), Survival: Night (Endless), Survival: Fog (Endless), Survival: Roof (Endless), Co-op Endless and Last Stand: Endless (iPad only).

Overview
The Giga-gargantuar absorbs 300 normal damage shots and its appearance changes after 100 and 200 normal damage shots before dying at 300 normal damage shots or four instant kills. The Giga-gargantuar throws its Imp after 150 normal damage shots or two instant kills.

Strategy
It has double health of a regular Gargantuar, making it able to take 300 normal damage shots or four instants. The Cob Cannon is a good plant to have in the player's arsenal; they just need to remember that they need to use Kernel-pults in order to use Cob Cannons. It is also a good idea to pack extra instant kills such as Squash, Jalapenos and Cherry Bombs. After two instants or 150 normal damage shots, a Giga-gargantuar will hurl an Imp into the player's defenses, unless it is already halfway into their lawn. The player should try to pack in as much instant kills as they can such as the Cherry Bomb, Jalapeno, Cob Cannon, Squash and Doom-shroom with a Coffee Bean. Sometimes, the Giga-gargantuar will appear before a normal Gargantuar appears.
