Peruvian Pufferfish
When a male injects a magic growing sponge egg toy with spicy peruvian peanut pepper sauce and, in the act of lovesqueezings, inserts it into any of his female counterpart's orafices. The magic growing egg expands, and the spicy sauce begins to irritate any skin it comes into contact with. Can cause serious damage to the epidermis and relationship.
Aleck pulled a peruvian pufferfish on his girl, the expandable dinosaur grew to 14 inches, and she couldnt get it out for 3 days. Now she'll never walk again.
