Missing power ups

[GeckoKid]

I had 2 powerups missing in my games where I couldn't figure out where to collect in temple grounds and toxic swamp, i eventually found the health powerup by pushing the rolling ball into the river from the main hub area, without even knowing what challenge it was.

I'm still missing one powerup at the toxic swamp anyone know of a particularly hidden one?

forum effect, i found both now

the only thing missing is the hole in one in the mirror's wake now!

Your post prompted me to go and finish collecting the power ups I was missing. I was short of two power ups in Toxic Swamp - found one trickily hidden on the top of the very first doorway and the other (also cleverly hidden) after the bridge. There's a green pod close to a rocky wall that will crumble, leading to a few gems and a power up in the end.
