Mr. Burke is Berserk, My Weirder School 4

My Weirder School weirder than ever! Mr. Burke cuts the grass, trims the bushes, and does the landscaping around Ella Mentry School. He wants to have a corn maze on the baseball diamond and drag races with his riding mower. What's up with the crop circles in the soccer field? And what did he bury under the monkey bars?
