Say Alice and Bob teleport together but suddenly a random teleporting accident happens and Bob ends up with Alice's body, and Alice with Bob's.
LEGO Body Parts is when someone switches any body part(s) between two or more people. Making this an appendage equivalent to a "Freaky Friday" Flip. Mind you, this trope is not just limited to teleporting accidents. Meat Grinder Surgery is another way this can happen; also, just simply interchanging body parts, which is by far most common.
Compare Easily Detachable Robot Parts. A subtrope of Physical Attribute Swap.

Toys
- Though construction toy brand LEGO is the Trope Namer, it's actually not all that easy to rearrange parts of LEGO minifigures - aside from their legs and hat, they're intended to be pretty difficult to dismantle without really trying. Of course it can still be done, more so nowadays since they started packaging heads separate from bodies, but it's not as easy to accomplish as you'd think. LEGO Themes featuring larger constructed humanoid entities like BIONICLE and Hero Factory play it straight with ease, and in many pre-Traveller's Tales LEGO video games this is exactly how designing playable minifigure characters tends to work. Also, it's rare that this trope in its conventional meaning comes into play in any LEGO theme's Excuse Plot.
- Mr. Potato Head has swappable body parts like this.
- The Marvel Super Hero Mashers line is based around this trope, having swappable body parts to mix and match your heroes and villains.

Real Life
- Transplants of any body part subvert this trope because the donor gets nothing in return. There are plans, along with excessive preparations and research, to transplant the head of a terminally ill man onto the body of a (then recently) deceased man to save the first man's life. This would be a historical first and, if successful, a major breakthrough in transplant science/medicine.
