Added for the Steam Summer Camp I guess, there's a new achievement on Toki Tori: Get a Tan. You need to stand in 10 sunbeams to get it.
I've heard indirectly from the developers that they are all in the forest levels. Does anyone have a list of which levels they are in? I have found 1-6 on Normal, but standing in it did nothing - can't tell if it was a wrong one, or just not working yet.
