Children from a primary school in Lancashire sent Sam on the trip of a lifetime!
He was attached to a helium balloon and travelled an amazing 15 miles into the sky, right to the very edge of space.
When Sam got that high he became detached from the balloon and the camera and he hasn’t been seen since!
So now the hunt is on to help find Sam!
Keep your eyes peeled for a white dog teddy who looks like he’s been on an adventure.
If you reckon you’ve found him or know somebody who has, let us know in the comments below!
