thomas and friends mini series

which piece are you missing, at first i thought i was missing one, but found it stuck in the box still, the small yellow connector.

It is the small yellow curved piece of track that attaches at the bottom, and it's definitely not in the box. Oh well, my son loves the loop, so he doesn't seem to care it isn't complete yet. Our James tends to flip in the loop, or on the exit. No problems with Thomas. We haven't tried any other engines yet.
