Wizzy and Zeeter befriend BREEZY, a gentle breeze, and learn all about wind. When they help Breezy become a bigger wind, she gets used by DELIRIA and CLOID, who want to blow down Zula Patrol Headquarters - but Zeeter and Wizzy get their friend Breezy to stop just in time. During a fun day at the beach, the ZPers are impressed when Gorga snorts out a huge sandcastle that's a replica of a real eroding stone castle on a nearby cliff. On exploring Gorga's creation, they get lost inside it and meet a 400-year old knight and his pet dragon - both made entirely of sand! The real challenge comes in trying to find their way out of the sandcastle before it erodes from the tide and collapses around them.
