Toad Stool HELP!!

[SleepyPirate]

Iv had a toad stool for about 8 months and about a month ago he stopped comming out, We had an algae outbreak around the same time but that has been corrected but still he has not come out even once and remains shrivled up. Can Anyone explain to me what going on he seems to be alive as he sheds and is still a bit slimy. Below are some pics of him now. He keeps acumulating algae on him and I try to keep up on rubbing it off but it seems pointless I think hes a lost cause..
