Players must define boundaries for the games. A player is chosen to be 'it' or 'the goo' and the others run. When tagged by 'the goo', players must joins hands forming a larger goo and continue chasing the others. Once the goo has three or more people, the goo can split into smaller goos and try to tag others. The last person caught then becomes 'the new goo' and the game starts all over again.
