[spelling or blending]

[viewers say the word]

Yeah, we just built the word.
We built it!
We built it!": Title: Runaway O. Build-A-Word: Box Description: Cat places a note outside her junkyard saying she is having a catnap. Kangaroo shows up to deliver a box to Cat and leaves it outside the front gate after seeing the note. Bear and Sheep appear to get letters from Cat's junkyard, but Bear sees the note, so they decide to wait. During which, they notice the box and wonder what is inside. Bear tries to find out by shaking the box, but this causes it to break into letters with the O rolling away. She and Sheep chase after the O, which leads them to Pig's barn where Pig is making doughnuts for his cooking show. Bear and Sheep catch up and ask if he has seen an O, to which Ant points out one of the doughnuts on the conveyer belt looking bigger than the others. Sheep recognizes it as their O, so Pig tries to catch it, but ends up tripping on the conveyer belt and sends it rolling away again. As Dog was showing Frog how to hula hoop, the O lands on Frog and twirls around his waist. Bear and Sheep appear as Frog loses control of the O and sends it flying, so the chase continues with Dog joining in. Meanwhile, Duck tries doing a cannonball into a floatie, but while in midair, the O lands in place of the floatie and gets stuck on his bottom when he lands. Bear, Sheep and Dog arrive and help pull it off, but it goes flying again and lands on the train outside the train station. They catch up with the train, but it leaves just as they notice the O, so they chase after the train. It comes to a stop at the junkyard where the O is thrown off and Bear finally catches it. They all put the box back together just before Cat wakes up and sees her delivery has arrives. She opens it to reveal it is filled with O's, but mistakenly tips it over and sends them rolling all over the place. She asks Bear and Sheep to help catch them, which causes them to faint and leaves her confused. Dog, meanwhile, starts chasing after the O's.
