Rival warlord whose own tank exploded, prompting Donut to blame Skull Empire sabotage.
Green Jiggly is invoked at the warlord council by Donut as evidence of how unorganized the other armies are: "Did you see what happened to Green Jiggly? One of his own tanks blew up!" She speculates it was probably built by the Skull Empire and asks the room whether anyone is sure they didn't just hit a button to kill the Jell-O guy, since they already said they can do that.
The jab lands—both Princess Vinata and Epitome Tagg chuckle at it. The incident sits alongside Tagg's announcement that his fleet has purged all Skull Empire hardware, suggesting the sabotage worry is real.
A gelatinous, Jell-O-like being, green enough to earn both his name and Donut's nickname for him.
Rival warlord and cautionary example of infected Skull Empire hardware.
