Building Blocks

The aliens are building too!

**Building Blocks**is the eighth episode of the third season of Numberblocks. It is the 38th episode overall.

## Story

Nine and Ten see something unusual: An alien, whose spaceship has crash-landed onto Numberland. The alien shows them her home planet, so Ten decides to rocket her there. She starts to count down, but the alien stops her and tries to build a tower with the blocks from the broken ship. Ten begins to point out she'll need more blocks to reach the planet, but then the alien suddenly levitates and "scans" her, rearranging her into strange and new shapes in the process. The alien begins to create inanimate duplicates of Ten's blocks, and Nine and Ten get to building a tower. The alien scans Nine and shoots out his shapes, and Nine builds with his blocks.

Six and Seven admire their construction. They then get scanned and their shapes come out. A montage of the Numberblocks building the tower of the blocks skips to the next morning, where they are getting tired, but the alien shows no intent on stopping.

Six points up to the alien's planet that the aliens are building their own tower. Quickly, they build the tower again until it almost touches the top of the aliens' tower, but when the alien shoots out a 9-block shape, it accidentally falls off the tower and lands on the ground, leaning against a block of the tower and causing it to become unstable.

Six, Seven, Nine, and Ten call for help, and Eight appears. The alien scans Eight, who starts rapidly building with his shapes, until the whole tower falls. The Numberblocks 6-10 hang on to each other at the edge of the aliens' tower for dear life while the alien climbs them to her home planet. Ten says goodbye to the aliens as she and the other Numberblocks safely drop down with her parachutes.

They feel guilty that their tower's all over the place, but Seven suggests they could build something else, and they end the episode building their own structures.
