Summer is just around the corner, and the kids of Ocean Shores are eagerly anticipating the annual Ocean Shores Surf Contest.
But when Otto, Reggie, Twister and Sam finally reach the beach, they make a surprising discovery - most of the sand is missing and the surf contest has been postponed.
Now, it's up to you to guide the kids through Ocean Shores, The Lakes, The Robot Factory and Mondo Mountain in a bid to find out who stole the sand.
In each area, you'll battle robot minions, make use of the new wave runner and zipline slide, and perform extreme sports, such as skateboarding and inline skating.
