It took a ton of turns of dice rolling, and monsters to take out as Brenda did most of the attacks, while you collected all of the items. Once the items were collected, you return to the amazonian village, and enter the witch doctor's hut, where you give her the items from the list she gave you, hoping that they'll be worth it.
"You both did well getting the things from the list for me," the witch doctor explains. "Not bad for a slime that use to be human, but as promised your slime days will be over. Just wait here, while I get the potion ready." You pass the time by looking at the clock, while Brenda used her gauntlet to carve into a log she found on the way here. The witch doctor finally comes back after mixing all the items from the list into 1 pot, and turning it into a sky blue potion for you to drink.
"The slime reverse potion is finished," the witch doctor says. "Just take a handful of it, and rub it on the core in your body. That should restore you to yourself. There is however a small side effect, though. You'll find out once the potion works on you."
