Using slime/honey blocks and sticky pistons on a redstone clock is glitchy.

Sticky piston and slime blocks on players

• The player randomly teleports when trying to bounce.

Sticky piston and honey blocks on players

• When on top of the block, it pushes the player on the side.

Notes: On mobs, the slime blocks behaves the same. When using honey blocks however, they sink inside the honey block.
