Welcome to the World of Harold & Spike!

Warning: Contains explosions, runaway hospital beds, and a very confused Jack Russell terrier.

Meet Harold.

He’s 9 years old, all elbows and knees, and the absolute King of Last-Minute Ideas.

He doesn't mean to cause chaos. He doesn't mean to blow up the school gym with a science fair volcano. He doesn't mean to "borrow" a neighbour's parakeet. It just... happens.

If you are messy, if you are sometimes late, or if your great ideas sometimes turn into spectacular disasters—you are in the right place.
