I don't really got at idea how to make a Spoiler booth or that stuff, so if you didn't finished the game- do not read it.
Well, I planted a seed in the hole, and in the smelly water.
I got no idea where to plant it next. anybody?
Hmm, it's been awhile since I played this game but I think I can remember.
Spoiler
In the Poom theme park, when you go on the roller coaster (the screen right before you meet than man with the beard), there should be an opening in the mountain somewhere, where you can plant the seeds.
By the way, to make spoiler text use (hide) and (/hide) except replace ( ) with [ ]
