Check for Interconnected Sprites?

I'm using the Board plugin. The board size is set to 8x8. I'm trying to figure out how I can select all sprites connected to eachother and put them into groups? By connected I mean having a logic distance of 1.

Say I these sprites at these logic X, Y positions on the board:

Sprite1: 1,1

Sprite2: 1,2

Sprite3: 2,2

Add Above Sprites to Group1

Sprite4: 7,7

Sprite5: 7,6

Add Above Sprites to Group2

Sprite6: 4, 4

Don't add above sprite to any group because it is not connected to anything.

And so on...

Thanks for any help you can give me
