This song was sung in Journey to Numberland, when Team Umizoomi was sailing with Square Beard over Shape Sea to retrieve the Star Key.
Lyrics
Team Umizoomi: Shapes on the sea
Shapes on the sea
Square Beard the pirate's gonna sail us to the key
Square Beard: Ahoy! Keep on the lookout for shapes out on the sea!
Geo: Like one giant oval and a trapezoid tail
Square Beard: Shiver me timbers! You've just made a whale!
Team Umizoomi: Shapes on the sea
Shapes on the sea
Square Beard: Square Beard the pirate's gonna sail youse to the key
Geo: Two rectangles in a cris-cross array, a crescent on the bottom...
Square Beard: And it's anchors away
Geo: Whoa!
Team Umizoomi: Shapes on the sea
Starfish: Shapes on the sea
All: Square Beard the pirate's gonna sail us to the key
