It seems to me that there is less "points" where the collectibles appear in the iPhone game than in the PC game. Especially (of course) for the butterflies. I never saw one in the graveyard, for example.
As for the mushrooms, I can see them only on the beach, near the big crate!
Is it normal or just in my iPhone game!!

The collectibles tend to appear in fewer specific places, but I have seen butterflies in the graveyard and elsewhere, as well as mushrooms in other places besides the beach. You're probably not watching the game as much as I did during testing.

Of course!
But I play a lot (my iPhone with the game is just here, near my keyboard! :D) and as I get the algae, I don't miss one mushroom!! I'm sure that they appear only on this place, at least when I play!!
It doesn't disturb me and I don't think that they are less numerous!

They are not less numerous, and I think it's kind of nice that musrooms appear very often in that one place. The other places are harder to see, so maybe you're just missing them?

Of course, I could miss some of them but I don't think so! Among the other places, there are several where the mushies can be seen easily. On the beach or in the middle of the village, for example! But, no. They never appear there!
It's strange but not disturbing!!

I have had mushrooms appear in the graveyard and at the edge of the mosaic, but not many!!!

I have played the game for 2 days now and keep my iphone logged in at work. I've only seen the mushrooms at the beach near the crate too. not that im complaining :P

*edit...my coconutes just replienshed!! yaa

I've got to agree. I only bought the game last night but that spot by the crate and the beach is the only spot I've seen mushrooms.

Awesome game btw. Loving it so far

i only seen mushrooms near the crate as well though i had butterflies in the graveyard
