This picture is mainly just showcasing the fact that I managed to find a way to get Bongo Bongo to work somewhere other than its boss room and face it with Epona. Notice how Bongo Bongo's hand is blue and how there are yellow damage sparks? (Link and Epona always have red damage sparks.) That shows that Epona is indeed able to damage it with a body slam. Epona can damage nearly every enemy in some way; most of them can be body slammed or trampled, but a few must be trampled, for some reason. In this case, although Epona can damage the hands and cause them to drop items, she cannot damage the boss's main body because you can't activate the Lens of Truth while riding her. Well, she might be able to damage it regardless, but I could never find the invisible eye in time before one of the hands recovered. Interestingly, if a hand grabs Link, you'll still have control of Epona. You can have Epona ram into the hand to free Link, causing him to instantly teleport back onto the saddle. Oh, and Epona isn't bounced into the air when Bongo Bongo beats its drum, which is pretty convenient.
