This is an unconventional one I thought up the other day. They are both players of percussion instruments. Both of them also break something during the course of the game; Bongo Bongo breaks the seal at the bottom of the well and Tijo breaks the ladder in his bedroom and decides to go on a diet because of it. They both also help you figure out who the protector of the nearby temple is... Bongo Bongo fought with Impa and was sealed away in the Bottom of the Well, just to later retreat into the Shadow Temple where Impa acts as the resident sage. And Tijo is the one who hints to Link that Lulu is the protector of the Great Bay Temple after he theorizes about the reason for all the madness happening in the area. So there we have it. The weird, evil demon thing vs. the rock star. --EveryDayJoe4
