Exit the GungeonXTG
Once rescued from a cell using a purchased Rat Key, Goopton will appear at random in NPC rooms in the main shop, operating his own storefront of goo themed items at a 33.333...% discount. Professor Gooptons dialogue is still displayed in Gleepglorpenese in Exit the Gungeon, however the lack of the Sponge item in Exit the Gungeon means that the only option availiable to players who wish to understand his dialogue is manual deciphering or datamining.
QuestXTG
After speaking to Professor Goopton a certain number of times, he will request that the player retrieve him Salt. Salt is a quest item, and can be obtained from snatching it out from under Resourceful Rat shaped balloons in Just Deserts Golf and Winchesters Original Game.
Delivering the Salt to Goopton will result in his children being absent on subsequent runs, replaced by ominous blood spatter on the walls and floor of the room.
Notes
- His room will be full of baby Gooptons that will bounce up and down.
- The player may have an effect on how high they bounce.
- Baby Gooptons under the shop machine platform will occasionally hit their heads into it.
Notes
- The characters and substitution cipher of Gleepglorpenese are taken directly from Alienese, a substitution cipher from Futurama.
- Professor Goopton is one of the few NPC's who will talk to the CultistETG.
