Tut tut, Xav, I explained this not long ago, either in the Picture Request Topic or the Q&A Topic, I forget which. Anyway, in the enclosure that most of the Mudokons are kept, get right up close to some of the giant wooden crates and you'll see the sticker on the side of it, telling you what it is. I forget exactly what it says, but it clearly mentions Molluck. Use the 'Check Quarma' button to make it brighter. You'll probably have to wait for the clouds to get out of the way, or rather their shadows.
And I just found
this thread while doing a bit of searching on the Forums. Nice coincidence, nice read. Enjoy.
