Royal Delight

The Royal Delight is a pet item that drops from the King Slime in Master Mode. It summons a pet Slime Prince, which follows the player around. If the player goes too far away from it, the slime will drop its crown and turn into a ball and fly towards the player. It has a 1/4 (25%) chance to drop.

Trivia

 * This pet may be a reincarnation of the Petri Dish Slime Pet from Old Gen Console and 3DS.
 * The pet appears to be the blue, male counterpart of the Regal Delicacy, a drop from the Queen Slime.
 * Its tooltip, "He answers to a higher authority", is somewhat connected to the Regal Delicacy's tooltip, "She is the higher authority".
 * Its sheer cuteness may give you the strength to defeat the Moon Lord with only a copper shortsword.
