Select one player to stay outside the pool and be the \"chooser.\" Everyone else is in the pool and one player in the pool is chosen as the \"tagger.\" The chooser chooses a body part such as arm, leg, nose, head, chin, foot etc. and yells that part to the group. The players try to avoid being tagged by the tagger on that specified body part. So, for example, if the caller says \"foot,\" the swimmers try to keep their feet away from the tagger. When the caller says another body part, that becomes the tagger\'s new target; the original body part becomes off limits again. Players who are correctly tagged join the tagger in pursuing the remaining players. The chooser acts as judge in case of questionable tags.
