It's Be Nice to Your Brother Day and Henry's got the chance to win a Gross DVD if he can be nice to Peter all day. How hard can that be?
In 'Horrid Henry's Favourite Day' he gets the better of Peter, finds a dog and goes on what turns out to be his "BEST DAY EVER" but when Peter and Henry play at being gardeners, nature starts to take over and in true Henry style the results are hilarious!
