Fall!

A lot of frogs and berries in the place of frogs and berries - you need a lift from the bird that made that nest, which can only see if you if you float up to meet it....

Yeah, those feathers are tricky to get

This was a nasty trick the devs pulled. I worked pretty hard to get the frogs to carry me up and into that teleport only to discover the "real puzzle" was in an entirely different place on the map.
