Learners select 2 other students to be the 'Crabs' (taggers). The Crabs assume the crab walk position in the center of the 'Ocean' (open space). The 'Fish' (all other learners) are scattered in the Ocean. When the music begins, the Fish 'Swim' (WALK only) throughout the Ocean. The Crabs move in crab walk position while trying to tag the Fish. If a Fish is tagged he/she immediately becomes a Crab and tries to catch other Fish.
