|“||THE KING DOES NOT PRETEND!||„|
King Sandy is a young boy who thinks he is a king and has a crush on Numbuh 3, who he considers his "princess", and later, his "queen". He is served by the "Knights of the Round Towel", who are actually his older cousins.
He was voiced by James Arnold Taylor.
Sandy first appeared in Operation: B.E.A.C.H., residing in an oversized sandcastle. He meets Numbuh 3 when his Knights bring him to his sand castle stating that she was found building a castle of her own on the beach.
He is intrigued by her beauty and asks her to be his queen - Numbuh 3, who believes this is all a fun game, says yes, when she doesn't realize he is serious.
He returned in Operation: K.A.S.T.L.E, his castle this time located "Rainbow Monkey Happy Sugar Land", and tries to force Numbuh 3 to marry him, threatening to dump several Rainbow Monkeys into a pot of boiling nacho cheese as blackmail to pressure her into marrying him. She is forced to agree to his terms. By the end of the episode, however, Sandy abandons his pursuit of Numbuh 3 and falls in love with her sister Mushi Sanban, who, unlike the latter, returns his feelings.
He also appears in the online game based on Operation: K.A.S.T.L.E Rainbow Monkey Rundown
