I think prior to doing anything,you have to identify the true cause without doubt,to avoid unnecessary handling and stress.
Don't you have a digital camera with a macro lens?In that case,wait for the bloke to be walking on a glass pane and take a close-up pic of underneath his toe.Same from above.It will show you if there are any shed remains or not.If it's the case,I would go for waiting for the next shed,it will probably come off without any human help,as long as its color is not dark (would show stress because of this toe problem) and as long as it still hunts and eat,not much worries to make for the time being.
If it was stuck with sugar as you said it walked into fruit mash,warm water would have been enough to dissolve sugar particles,at least,I would say so,make yourself the test with a bit of sugar in the water and work out yourself the time needed for sugar to dissolve :lol:
Or sometimes their toes give the visual impression they have been twisted or cross each others but it soon comes back where they should be :lol: Hope I made everything clear,English is not my native language :wink:
