The Energon Pub

It'd be nice to know what issue is being fixed... or really, any background whatsoever...

Basically, it's really hard to plug the end of his tail onto those grey tabs with the posts, because the posts are ever so slightly too large for the holes, so sand down the posts.

Or make the hole larger.

Or just twist the tail pieces a little as you push them down.

Or use a little grease.

Or cut a groove into the posts so they can compress.

But the video shows you how to sand.
