No worries! My toads go through there "phases" (it seems) too, hibernation mode, low food intake, high food intake, etc.

Both my toads did this about two weeks into winter, they'd come up every 2nd or 3rd day and eat, just let them do there thing, once they realize they don't have to hibernate, they'll be back to normal.

Also, if you want to bring them up without actually digging them up, just pour water where they are burried, and they will generally make their way back to the surface.
