Ruined Childhood Series: Gourd Little King Kong's Substitute Attack

Are There Any Books That Ruin Childhood (Requires a Higher Score)ʘʚʘga?

Preferably one about Bears. I read a copy yesterday, but I can't find it. I hope someone with good intentions can help me find another one. It would be best if I can find the one I read yesterday (●'◡'●)
