To his family’s frustration, Henry is skilled at making trouble, from babysitting pets in his bedroom to starting a shark panic at the swimming pool. He is a mischievous prankster-type kid, who is exhilarant and arrogant. He is much hated by some of the staff at Ashton Primary School (his school), like Miss Battle-Axe and Mr Soggington but is a very popular kid with the students, having lots of friends, most likely due to his prankster-type personality.
