Trivia

 * Prior to version 0.9, the chicken could lay eggs that gave Farming XP like a normal chicken.
 * If the player kills only the chicken or the rider, and not the other, they only receive the drops from that mob. If the player kills both the chicken and the rider at the same time with a weapon like the Ink Wand, they receive the drops for both mobs. It is unknown if this is a glitch or an intended feature.
 * The Aspect of the Dragons' ability does not work on the Monster of the Deep.
 * Prior to a fix, the Fishing XP from killing the Monster of the Deep counted towards the XP required to spawn Revenants even though the message from starting a Zombie Slayer quest specifies that Combat XP is required.
