Other Castle

The other castle is found in Pikmin 3: The Dweevil's Revenge/Pit of 100 Trials. It's a gray "Cuatro" Lego Block. It was named after the line from Super Mario Bros. "Thank you Mario, but the princess is in another castle" without the quotation. It yields 100 pokos, which is as much as the Costly Blanket. Oddly, it looks only a little like a castle.
