Gargantuar

Overview
The gargantuar is a massive land zombie that carries an imp on its back. It has a huge amount of health, and takes two instant kills (cob cannon ammo, doom shroom, cherry bomb, squash, etc. ) before it dies. .When it gets low on health, it throws the imp at your house. It uses what it carries (road sign, telephone pole, other zombie) to crush your plants, and if it is given enough time and it doesn't die, it will leave nothing at all on that row, not even spikerocks and spikeweeds. When it dies, it roars, sways, and falls over, landing with a ground-shaking thud. It will throw the imp after one instant kill hits it or if you give it enough damage otherwise. According to the almanac, it doesn't have a girlfriend.

Suburban Almanac Entry
Gargantuar is a gigantic zombie.

Toughness: extremely high

When Gargantuar walks, the earth trembles. When he moans, other zombies fall silent. He is the zombie other zombies dream they could be. But he still can't find a girlfriend.

Strategy
You can block these off with spikerocks, which take several whacks before they die. Make sure that you hit it with at least one instant kill, or else it will probably do a lot of damage to your defenses. It also works well to slow it with a winter melon or snow pea. Cob cannons are useful against these, and chompers are useless. They go biting away and nothing happens, except that they get crushed. You can also try to slow it by planting something cheap (sunflower, potato mine, etc.) in front of it. Hypno-shrooms do not work, because they just get squished, even when planted directly underneath. rows of gloom shrooms along them work as well, and in survival endless, you can stagger it a bit so that the gloom shrooms in the pool kill them before they get to the ones next to the pool. In I, zombie (Me smash!), these are useful in hard rows without squash. In vasebreaker, save some squash to get rid of these guys, though potato mines work as well..

Giga-gargantuars
Giga-gargantuars are the same as gargantuars, except they have red eyes, about twice the health, no almanac entry, and probably only appear in survival: endless. Use the same strategy, but you might want to hit them with two instant kills. These take three instant kills to kill, and two to throw the imp.
