Otto is a local resident of the Sea Star Aquarium in Coburg, Germany, and he’s starting a rebellion. At first it he tried redecorating his tank a few times, but when that diidn’t satisfy his boredom he started throwing stones at the glass, and juggling the neighborhood Hermit Crabs.
These days Otto has moved on to new and more dangerous tricks. Staff were forced to camp out near Otto’s tank to witness his newest tantrum. They discovered that Otto became annoyed by the bright light shining into his tank and discovered that he could extinguish it by climbing onto the rim of his tank and squirting a jet of water in the lights direction. This short-circuited the light and the whole electricity supply for the aquarium and threatened the lives of the other animals when the water pumps stopped.
