Topic: LEGO Friends and LEGO System relations
Don't be afraid of the title of this topic! I made a topic to discuss how LEGO Friends (especially the mini-dolls) can connect to the LEGO System parts, because we were going way too off topic on another thread about this.
So, from my experiments, you can connect the LEGO Friends mini-doll parts to standard LEGO parts in many ways, though, most of them are not legal. Creepy, yes, legal, no. Even if you don't like LEGO Friends, look on the bright side, you can make some pretty crazy aliens and such out of them.
Top-left: Mini-doll neck is standard LEGO pin (lightsaber stick sized). To connect a LEGO Minifiugre head, use a 1x1 round with a hole in it.
Top-right: The leg connection of mini-dolls connect to standard LEGO clips. The connection isn't the best, and is definitely not legal, but it opens up new MOC abilities.
Bottom-right: A LEGO Ninjago snake head (with a connection that is slightly larger than a LEGO 1x1 connection) fits on the LEGO Friends legs diagonally.
Botom-right: The bottom of a LEGO Friends torso allows a standard LEGO bar (like a lightsaver stick) to slide in, but the connection does not fit perfectly. It probably puts pressure on the torso and the stick slides around inside.
Please share your discoveries too!
