Ice Bulls

The Ice Bull is seen in "What is Life?". The Ice Bull is made of ice and organs. It guards the Ice King's castle and chases intruders. It chases Finn and Neptr and runs into a lightning bolt shaped door, which causes it to shatter and spill its organs. It is possible that the Ice Bull is summoned by the Ice Toads' alarm. It is unknown if it is common in the Ice Kingdom or if it is a one of a kind. It is the only ice monster shown with organs which caused its death.
