Stuck in Kelp Forest and kind of everywhere

[Mononoke]

Hey,

i'm a little bit stuck in the game. First there is an area in the kelp forest which is sealed by a door that needs one of those white balls but i can't find it anywhere in that region!?

Then there are some spots around Aquaria where there's hot steam blocking my way. I can't swim through it, but it goes further beyond them.

Well, i guess it would be a great help to know these two things for a start or at least get some hints. It drives me crazy, i've been swimming around in circles for the past few days.

Not to keep you stuck, but I'm not giving proper hints until you say what forms you have.

If you have the form you get in kelp forest you can open certain plants/flowers with seeds.

Thanks a lot for the hint with the plants. I'm now going to check them all out :-)

You can also get past the steam with a form recieved in Mithalas
