From the chemical-spilling pollution factories of Trope Co.®, it's Mutagenic Goo™!
Mutagenic Goo™ can do anything! Just apply our Mutagenic Goo™ onto anyone or anything and watch as it works its magic! What does it do? It can do anything! It can imbue animals with humanoid forms, turn loser-wimps into hideously deformed creatures of superhuman size and strength, mind-control people into eating it, make trees kill people with terrible special effects... or it could render you a puddle of goo on the sidewalk.
Mutagenic Goo™: It's The '80s, and Toxic Waste Can Do Anything!
Whatever you do, do not inject, touch or be within a minimum of 10 yards of Mutagenic Goo™ without a protective hazmat suit.
