I dont know if its dying or not. When I first got it he went into the castle and hardly ever came out. OOPS!!! Forgot to mention I got it from a guy and it was already 6 inches. So anyways earlier today I noticed in was out but instead of doing the normal sucking on any object it can it was just laying on the gravel. A few hours later it was sideways(not completely upside-down...but stange to see). So I gave it a nudge with the net and he took off. A few hours passed and I saw it on the back of the castle and it looked like it was sucking on the back. When I looked though, he was just kinda standing there not sucking at all. What should I do?
