Jungle Taitei - episode 29 - 19 Apr, 1966

Something strange happens when Dr. Spree's flower experiment turns devious, for those who smell the obscure flower end up having violent, brutal nightmares, which results in the animals turning against each other. This unfortunately also causes them to be unsure as to what is a nightmare and what is reality. It is up to Kimba to investigate the problem. (Source: Wikipedia)
