George and Harold get a chance to meet their future selves as they are trying to save the world from an evil genius gym teacher who has created a smelly mind control method for children.

Tons of action and the end of Captain Underpants, this is a must read if you've followed the saga previously.

I liked how the look in to Harold and George's futures worked, but I got really, really, REALLY tired of all the puns. Most of the puns will go right over kids' heads, but it was incredibly distracting as an adult reader.

Grades 3-5+.


This had a few laughs but it wasn’t as good as the other ones. I found “Say hello to my stinky friends” really annoying for whatever reason. However, I am bittersweet that it ended. Harold being gay isn’t my favorite but upon third read in 2025 I’m trying to be a little more understanding.

Oh my ehehe can't believe you can get away with that type of sadistic-satire humor in a kid's book plus aww it's good to see George and Harold end with...drawing what their love most, comics:)
