Jungle Taitei - episode 36 - 07 Jun, 1966

Three of Kimba's friends get lost in a haunted valley, which is rumored to house a legendary monster. The creature, however, is merely a rare giant bird, the last of its kind, seeking shelter here, and out of compassion Kimba invites him to live in the jungle. But this kind invitation brings a lot of trouble. (Source: Wikipedia)
