Ackpows are sphinx-hat wearing servants working for Mitsy in The Flip Flop Show. They 're featured in Chapter 2-3 inside Merlee's Mansion. Ackpows' roles are to make sure all of the other servants are working and pay them Rubees after they're done. Also, if Ellie glides to the door above the level start, she can find a Question Block containing a Mushroom. Every time Sacre or her jump under the Question Block, they have to pay ten Rubees to the Ackpow watching it. According to Sipsi, they act like they're all important, but in reality, they're in debt to Mitsy just like every other servant. This is very similar to the system of work the Egyptians used.
