I decided to limit remakes to new bosses that they added, otherwise half this video would be fights against Boom Boom and Birdo (since SMB2 and SMB3 got two remakes each).
i notice every koopaling except for ludwig in super mario world are pairs, meaning they share the type of fight iggy and larry- you fight them on an island floating in lava lemmy and wendy- they appear out of pipes and you need to find the real one since fake dummies also appear morton and roy- they climb on the walls and onto the ceiling to drop onto you
