Giga Impferno-coaster

Giga Imp Inferno-coaster is the boss of Imp World. He is driving a 'hot rod' roller-coaster shaped as a worm with one eye. There are tracks on the first column to the right and random ones lead to the column, giving the Inferno-coaster a place to attack.

Overview
The Giga Imp Inferno-coaster absorbs 1,500 damage, and its appearance changes at 301 and 600 before being destructed by the plants.

Summons
At its normal health, it summons:


 * Imps
 * Imp Punts
 * Giga Imps (just Imps with sunglasses and 2x health)

At its first degrade, it'll summon a roller-coaster track that reaches the lawn mowers and it doesn't summon Imps anymore. It summons:


 * Imp Punts
 * Giga Imps
 * Mascot Imps
 * Gargantu-imps

At its second degrade, it plants one more track. It doesn't summon Mascot or Giga Imps anymore. It summons:


 * Imp Punts
 * Shopping Cart Imps
 * Double Bucket Imps
 * Gargantu-imp

Strategies
You are given all plants from PvZ 1, with the exception of the Jalapeno, Cherry Bomb, Split Pea, and Starfruit, plus the plants not in PvZ 2: IAT. Use Squashes and Potato Mines wisely, as you are only given ten each for the entire fight. Melon-pults and Winter Melons are useful, albeit very rare. Threepeaters are useful for destroying zombies on tracks.

Trivia

 * This is the only time a Giga Imp can appear.
 * If the Inferno-coaster summons a track where there are plants, it'll demolish the first two plants in that row, then stop.
