Sea Princesses

The princesses are heading for their first day of school when they come across a lost whale; Tubarina takes the pearl from her father's scepter for an exposition.

Ester's grandmother is due to arrive at the Starfish Palace any minute, but Ester has more important business to take care of; she must journey with her friends to Dryland to help rescue a beached whale; Ester's conscience starts to play tricks on her when she keeps a pair of penguin-shaped earrings she finds in the sand, knowing they more than likely belong to her friend, Isa.

The princesses escape from their babysitter and go to the Royal Ball; Leo is sick with worry and can't lead the whale migration.

Polvina's diary is stolen; Polvina and Tentie find a beautiful box with a toy inside.

Ester and Polvina rush to school with such a pace that they clumsily smack into the Turtle King, and his crown gets knocked off his head and snapped up by a boat's hook; Ester and Marli confidently set out on their first babysitting job.

Elektra returns from a long trip; the crabs invade Polvina's home forcing her to sleep one night in Tubarina's and Ester's home.
