S1·E4 Blocks

'I did like my tower but it was more fun making a rainbow tower with Coco!'

Bing is busy building a tower as tall as he is with his blocks, and is upset when Coco arrives and hijacks the blocks so that she can make a rainbow pattern with them instead. When even Charlie wants to play with the blocks, it is clear a new game needs to be found so that they can all play together.
