Horrid Henry: The Good, The Bad and The BuglyHorrid Henry: The Good, The Bad and The Bugly

The game begins with Henry explaining to the player that life would be good if it wasn't for "wormy-worm little brother", as Peter is crying because he has lost Bunny again and Henry is at the blame. Henry decides that the only thing to do is find Bunny, as he teleports away.

In Lovely Land, Henry upgrades his Goo-Shooter but does not find Bunny anywhere, with Peter still crying. Mum asks Henry to do his homework, but Henry says to the player that he would rather be battling bogey-brains. He begins to wonder if Moody Margaret has anything to do with the whole thing, likely wanting to get him into trouble.

In Purple Hand Gang Land, Henry defeats Mar-Grilla and upgrades his Goo-Shooter once again but still no Bunny in sight. Henry is beginning to get annoyed, while Mum tells him to not be Horrid. Henry then notices a bogey coming out of Peter's nose and gets an Eureka! moment, and reminds himself of the Evil Emperor.

In Gross Land, Henry defeats a purple octopus and retrieves Bunny. Peter is happy to have it back, and Mum reminds him to do his homework again. Henry realises he has forgotten and asks Peter to do it for him. Peter doesn't hesitate and goes off. Henry thanks the player for helping him and they'll always be honorary members of the Purple Hand Gang.
