What do you do after you get the translation key on shark tooth island?

On Shark Tooth Island, the missing page from Professor Hammerhead's journal has the translation key. The girl had it but it blew onto the roof of the ruins. To get it, push the big block right, and jump to the vine. From the first platform, you can jump hard left to the roof. The translation of the symbols on the face are (top teeth) B O Q N (bottom teeth) S P E. From left to right they are BSOPQEN.

So, you press the 3rd symbol, the 4th symbol, the 6th symbol, and the 7th symbol (from the left), spelling "OPEN", then press the nose.
