Thanks for telling me where you were. Here ya go!
Alright, head to the Hippo's Lagoon. Now there are two ways you can go to get back to the tree house. Here's the first way.
As soon as you enter the Hippo Lagoon, walk forward a few steps and press the L1 button, it should lock onto a vine on the wall. Jump on that vine and climb to the top, then swing through the vines at the top to get to the tree house.
That's the long way. So I suggest doing it this way. When you enter The Lagoon, turn towards the hippo in the water and jump onto top of it, then from there, jump to the next piece of land. Immediately jump in the water and swim to the next hippo, wait for him to go down under way and then swim ontop. He should float back up with you on top. Now before he dips back under water, quickly jump to the next piece of land with the "Treasure Chest" and the other vince. Open the chest for the 101 Dalmations(P.S. This is what's required to get the sercet ending) and then climb up the vine to the top.
Once you reach the top, press L1 and look for the vine, and climb that up to the tree house.
There you go!
