I just finished reading Captain Underpants and the Revolting Revenge of the Radioactive Robo -Boxers by Dave Pilkey. The two main characters are George and Harold. The story starts of with George and Harold were turned into evil zombie nerds. Then Tippy Tinkle Trousers  made a time machine so he could go back in time. As tippy tried to get George and Harold  they ran into the library and ran up the stairs as their mean principle chased them. George and Harold luckily  got in the time machine and went 65 million years ago. So Tippy transported himself to 65 million years ago. When tippy finally got there he saw them up in a tree,so he started to kick the tree down. Then when captain Underpants tried to Destroy tippy, tippy dropped a bomb that had a 45 seconds  on it till it exploded. Then the bomb blew up but everyone was gone so no one was near it. But when captain underpants tried to stop tippy he tied him to rock. Then tippy saw George and Harold in a near by a cave peoples village. So tippy stomped right threw and destroyed everything in his way.The cave people survived tippys destruction  so George and Harold made a comic for them to show how mean tippy is. After that the cave people came with plans to take down tippy. They started the plans tippy got tripped and covered in mud. After he fell in mud,they pushed bolder`s of a cliff and on his head. After torturing  tippy they thought he was done but he came back and took his big beam and froze everything. Then captain underpants  got free and  saved everyone and destroyed tippy.By: Austin Kilduff
