**Collect 40 Pustosser Tumors for Cypress
**Bring the remains to Cypress
**Wait for Cypress to study the specimens
**Return to Cypress
thumb|An optional path to quickly get 40 Pustosser tumors. In this you will hopefully gain 5 tumors per run.
One of the oddest creatures is the Pustosser, which grows tumors on its body filled with Haze, which are then torn off and thrown at us- but you of course know that. I'd like to get some samples of these tumors to study them and figure out how their bodies could be growing these things.
When a Pustosser combusts, it usually tosses off a few tumors, but occasionally one will land on the ground without breaking. If you could bring me 40 of these Pustosser tumors, it would help my research a great deal.
We know that fungus produces the Haze that plagues us, but some Mimics also seem to use a form of Haze when attacking us. Are the Mimics capable producing it, or do they harness the fungus somehow to produce it?
