This zombie does not have its own icon in Garden Warfare, although it does in Garden Warfare 2.
Although this zombie does not have the animation of trapping in a Spikeweed in Garden Warfare, it has its own Gooped, Burrow, and swallow animation. All of these animations are then reused/recycled in Garden Warfare 2 for the new Imp class.
In Garden Warfare, its only difference visually from the Imp Punt, besides the fact that it walks, is that its dynamite fuses are not lit until it is about to explode.
However, in Garden Warfare 2, they are lit the whole time that it is running.
It can be heard laughing frantically when it is running in Garden Warfare.
These are slightly different than the ones used by the Exploding Imp.
Zombie heroes in Solo Play of Garden Warfare 2 summon these instead of regular Exploding Imps, as players in online Gardens & Graveyards cannot summon Exploding Imp Fans, only Exploding Imps.
These, along with Yeti Imps and Exploding Imps, appear to explode and leave a fiery trail in the air when vanquished, even if they are eaten by a Chomper.
