well if found a glitch (requires too many items) that allows your character to remain on its side, doing this glitch will remove all the items from your inventory and put them onto the ground, to get on your side too many items IS required to accomplish this strange mission.
1. climb up a tall cliff
2. jump off
3. open up your inventory
4. spam click the heart shaped button
5. go in to 2nd or third person view to see the outcome
now your character will remain on its side till you die again :)

thankyou for reading this useless (but funny) glitch XD
(im not sure if this works on multi player, but it should on LAN
