In Super Mario Advance, the bosses Fryguy and Clawgrip have new introductions, which show what they looked like before being transformed to fight the player.
Two of the other bosses, Mouser and Tryclyde, also have working introductions (with new graphics included) that go unused. Readding them back to the game reveals, however, that these unused intros are somewhat unpolished compared to the used ones (for example, neither Mouser nor Tryclyde’s original forms have animations despite a second frame existing in the game’s data).
This hack restores these unused introductions for Mouser and Tryclyde’s boss fights in Worlds 1 and 2 respectively. Additionally, these introductions have been touched up a bit to make them more in-line with the used boss introductions.
