The Baby Spin is a move in Mario & Luigi: Partners in Time.
Description[]
Baby Spin is a height-gaining move used by any of the Mario Bros., which include Mario, Luigi, Baby Mario, and Baby Luigi. To execute the move, Mario and Luigi have to move into their baby counterparts during a Spin Jump. In doing so, the babies are forced into the air, spinning as they descend. Baby Spin can be used to hit blocks and switches on certain ledges that not even Baby Toss can reach. If the Mario and Luigi try to spin around Baby Mario and Baby Luigi before they learn the Baby Spin, the babies only do a low spin before dropping instantly.
In Mario & Luigi: Partners in Time[]
Both Baby Spin and Baby Cakes are taught by Toadsworth and Toadsworth the Younger after the Mario Bros. complete Gritzy Caves, but before they head for Thwomp Volcano. Once both moves have been taught, the Mario Bros. have to rescue Baby Peach using the two moves.
