A review by booksonstereo_o
The Adventures of Ook and Gluk: Kung-Fu Cavemen from the Future by Dav Pilkey

5.0

1. George and Harold as cavemen, what else could you ask for!
2. Great villian and use of time traveling even though it got super convoluted
3. I had such a fun time reading this and I miss the captain underpants series so much

Full Captain Underpants series review coming soon to my Youtube channel!
