Establish boundaries. Start by calling yourself the Blob. Chase the children until you catch one. That child then grabs your hand and becomes part of the Blob. Together, still holding hands, you catch others. The Blob grows larger with each capture. Only the outside free hands can tag. The Blob may either tag or encircle its prey. One of the characteristics of the Blob is that it can split up in to different numbers of smaller Blobs, but there must be at least two to a Blob. When one, two, or three children are left, whichever you specify, the game ends. Those children unite and begin the next Blob.
