The door to the rust bucket is pushed open, Ben and Gwen jumped on wearing their swimsuits.

Ben/Gwen: WOOHOO! THE BEACH!

Both Ben and Gwen ran towards the water, Max And Ryder walked out of the rust bucket.  Ryder wearing, a blue swim trunks with a greyish trims.  Max closes the door behind him.

Ryder: Ok, I gotta be honest.  I'm surprised that we are in Australia.

Max: Well, we do have Gwen to thank for winning this trip for us; besides it's feel good to be at the beach.

Ryder: Ture.

They walked onto the beach, they noticed various people building sandcastle.  They noticed Gwen and Ben looking at a sign.

Ben: So, there's a sandcastle building contest.

Gwen: Well, sandcastle are big in some places; believe it or not, people actually come to the beach to watch sand castles.

Ben: Uh... What?

Ryder: Basically; whoever builds the better sandcastle wins a trophy.

Ben: Oh... Well, I'm going swimming; later.

Ben turned and heads towards the water.  Gwen is sitting down, on a beach chair; reading a book while Max and Ryder are tossing a football.  Just, Max threw the football various people screamed and ran away; everyone looks as Gwen sighs.

Gwen: What did they doofus do this t-

Four arms crashed landed in front of them, he groans rubbing his head; Gwen hits him with her book.

Four/Arms: Ow! What's that for!

Gwen: Why did you scares those people?!

Four/Arms: But I didn't scare them.

Gwen: Then who did?

Four/Arms: *point* That!

The trio looked as, they noticed a Coral monster walking out of the water and onto shore.

Gwen: Ok, that's new.

Four arms stood up and ran forward, Ryder primes his bracer and scroll through his aliens.  He press down on the faceplate; He's brought to the void as his whole body turned into sand.  The sand grew, as a single eye appears while his hands are turned into sand claws.

Max and Gwen looked, and see Sand cyclop.
