How do I make a snake\nibble movement?

Hi. I'm creating some kind of Nibble (Snake) game clone based on the RexRainbow's Board (tiles) and Chess movement.

I have main part and tail parts. The logic is that after every movement of main part first tail part moves to main's previous XY.

And that's where i'm facing a problem: how can i make second, third etc. tail parts follow their previous tail part?

Thanks for your interest and help.

Well, any other way (example, sample) to create good old snake is acceptable and highly appreciated.

I'm knocked out with "LastBodyUID = -1". So the first part linked NOT to head will be linked to UID = -1?

Oh, oh, everything is ok. Thanks.
