The Dink Network

i dont think that is supposed to happen at this point in the game, im trying to get past the trees that are blocking passage to the southern part of rai island. according to the walkthrough, of which i only read a short enough section to try and help with this apparent problem/bug/whatever, it says once i know the trees have to be removed im to go talk to the wizard in the northmost house of the island to find out what i need to remove the trees, which apparently is a potion to turn me into a duck, i guess, so i can sneak past the old lady in the house. problem is he isnt giving that option to me he says he doesnt know how but someone else might the others are all saying the same thing or they just dont know. so im thinking something is wrong with the game, although i may have missed something entirely, i even redownloaded it and tried again with the same result.
