Yogibear,

Im not sure if the algea is required to solve the puzzle,, i ended up having to restart a new game cause they all died of starvation,*my fault lol* and i let them totally overfish the ocean, when the algea apeared i got level 2 farming and started with the cocnuts and its been wonderfull since, and to top it all off, i am not having the food glitch everyone else seems to be having, they work just fine while im away. But no harm in trying though see if you can get the algea puzzle without the algea acually showing, if it doesnt work, sit there and put them in over and over again till you got it. best of luck

PS ,, i love how you miss spelled dam and LadyCF edited it out lol
