Help Pick Up Trash for Burgess
When you wake up one day a few days after completing The Show Must Go On, you’ll be greeted by a cut scene where some Geeglers are invading the Oasis water reservoir. You’ll want to head over there as soon as possible to help out Burgess, who’s being subjected to them throwing trash at him. When you reach the reservoir, Burgess will ask you to help him clean up the trash they’d thrown around.
There are 5 pieces of trash on the ground. There are 2 pieces next to a tree near some stairs up to the Water World store, and then 3 next to the lake bank near the statue.
Once you’ve picked them up, speak to Burgess and he’ll thank you for your help by rewarding you with +1 Water barrel. YOou’ll also earn +5 Burgess Relationship and +50 Gols.
