Odd disapearance

[Dragonesque]

My snake has vanished, but it's enclosure was sealed tight and there don't appear to be any holes or cracks. My Mom thinks he might have been stolen, but he has been gone since yesterday, possibly the day before. I think someone like one of my siblings went in my room and maybe opened his tank and let him out and isn't being honest about it. I have looked around my entire bedroom, under chairs and couches, the dryer and refrigerator, but I can't find him...
