Stephen Hillenburg's Hawaiian Shirt

Origin
Stephen Hillenburg is a marine biologist and cartoonist and creator of SpongeBob SquarePants. In 1997, while pitching the cartoon to Nickelodeon executives, Hillenburg donned a Hawaiian shirt, brought along an "underwater terrarium with models of the characters", and played Hawaiian music to set the theme. The setup was described by Nickelodeon executive Eric Coleman as "pretty amazing".

Effects
Whether it is worn or not, whenever the shirt is near marine life, it will anthropomorphise them in the same comedic style as the original seasons of SpongeBob, with exaggerated voices and characteristics. When worn, it instills the wearer with a love for marine biology. However, wearers will eventually abandon many things tha they were previously involved in, often leading to bad results.
