What in the crap?!

It sort of sprouted…

Any suggestions?

Looks like damping off, which is a symptom of having too much water in your grow medium. Seedlings need very little water and it is best for them to get their water from humid air. It can be accomplished by inverting a clear cup or a cut pop bottle and spraying in the bottle a couple of times a day (and not watering the soil, or at most a couple of ml of water in the soil every few days)

what can i do for this one?

Probably not.
