Kingdom Hearts 358/2 days Pence's Quiz...day 77... I think

Can somebody tell me what to do on day 77(I think it was 77) or...I'll just call it Pence's quiz if I got the day wrong it' the one where pence and the girl are talking and the fat dudes in the underground.

go to the undergrund and talk to pence then go back to hayner and olette then go to the usual spot and look around and then go back to the undergrond and answer 3 then 2 and 3 and then go on with the story.

Then what do you do?

go to theforest an hit a tree that has fallen leaves.. then it`s boss battle time!!
