Strategies
With
This zombie is a really strong one. With a massive 7/7 for just 6, he can destroy tough plants while surviving powerful attacks like Template:PvZHLink or Sizzle. If he gains traits from Wizard Gargantuar and/or Smashing Gargantuar, or is played on an aquatic lane when against Solar Flare, Chompzilla, or Captain Combustible, this can easily end the game in the favor of the zombie hero. In PvZ 2, this zombie smashed things, but in PvZ Heroes, it throws its club.
Because he has the Amphibious trait, you can also play this on an aquatic lane. Since most Amphibious plants are not as powerful as most ones without the Amphibious trait, he can survive a few hits in aquatic lanes and land heavy damage on the plant hero. Using Vitamin Z or Galvanize on him will make him even stronger and turn him into a huge threat for the plant hero.
However, because of his high cost, this zombie can only be played later in the game, when the plant hero can also use powerful cards to deal with Deep Sea Gargantuar. You can play Gargologist to allow him to be played at least 2 turns earlier. However, this combo can primarily only be played with The Smash.
Against
This zombie is one of the strongest Amphibious zombies, and the only Amphibious plants that can destroy him are Template:PvZHLink and The Great Zucchini, but even they will get destroyed if unboosted. Template:PvZHLink can destroy any zombie, so it is also a good counter against him. Shamrocket is an even better choice, as it can also destroy Deep Sea Gargantuar for a cheaper price than Squash. Another strategy is using Banana Peel, Whipvine, Template:PvZHLink, or Template:PvZH Link to move this zombie to a ground lane if he is on an aquatic lane, so he can be in range of Template:PvZHLink, Template:PvZHLink, or Scorched Earth. The Great Zucchini, Transmogrify and Template:PvZH Link are also effective choices to use, which all turn this zombie into a much weaker zombie.
