Good grief! The Blockhead is taking everything that’s square-shaped, so that he can build a tower of blocks up to the sky! To track him down, Bo and Dezzy have to waddle like Penguins past some ice block-cutting Walruses, then climb like Monkeys over a very BIG bay’s castle! The baby rewards them with a Magic Block Making Block, which they give to the Blockhead, and stop him from taking every block in the whole wide world!
