is my blue linkia dead?
 

one of it's foot is up side down and it hasn't move from one spot for 3 days.

Lift him up and look to see if his feet are moving. If you cant see them then hes pretty much dead. I think they also smell too when they die.

Is it starting to turn white? If so then it's on it;s way out.

it's still very blue. looks like when i got him. do they retract their legs when they get lifted. ?
