Please help me how do u get to that fonten thingie upstares

Can you write clearly? What do you mean by Fonten? Do you mean fountain? You can't go there at all unless your doing a sidequest with the Eggs

lol yes you can climb the door knob then use your helicopter over to the place were u normally enter the bedroom (the peep hole ..lol but u have to climb from that little pic of them) after that helicopter over to the table with a big flower on it then on the crown molding of the wall walk from there there will be a string to climb i guess its up to u to use it its like space in the top and theres a chibi door so then when your near the water fall just go in (the frog ing is stuck there go to the far left of the rocky part and with ure blaster shoot the stiker then turn off the waterfall hope I helped!
