The word “sisid” means dive. The sisid kids seem to fish in the water but instead of feeding them fish treats, they will wait for the boat and ask for the passengers to throw pennies. Compare to other kids who play in the playground reading books in the land surfaced area, these kids were trained to dive in the seaside for their leisure, playtime and same time to dive coins for school allowance. Some of the sisid kids are waiting in the large sea vessels docking station expecting a large amount of pennies.
