Mary Had a Little Lamb
If the player waits for one minute after throwing the final metronome to the final Umotomat in the first area of Planet Sonata before encountering the mini-boss, a rendition of "Mary Had a Little Lamb" will play.
Bonus jewel in Planet Sonata's mini-boss
If the mini-boss of Planet Sonata is defeated before the first wave of Chibis appear, an Umotomat will fly in from the right and drop a Yellow Jewel worth 10,000 points. As the bobbing heads move quickly in randomised patterns, this is incredibly difficult to do, though a player with quick-enough reflexes can land three hits on one of the heads during the mini-boss intro.
Old stage select
An early text-based stage select can be accessed using the following Game Genie codes depending on game version and pressing :
- NTSC-J: BZ6A-AAHG + AP6A-AZ9J
- NTSC-U/PAL: BZ6A-AAH8 + AP6A-AZ2A
To navigate this screen, press and to select a level. Note that in the International versions, there is no text displayed as the font used for this screen has been removed, but the stage select is still functional.
Pro Action Replay code FFFE05:08 will enable a slow motion mode, cutting game speed by half. Be warned, as the game will freeze after completing a stage when using this mode.
