Doraemon (1979)

Space Tarzan (2) (1x134)

:

After a few narrow escapes, Doraemon and Nobita feed mealie pellets (which make any animal tame) to a load of dinosaurs. Doraemon fixes his time machine to a hut door so when Tai and his producers walk through the door, they are 150 million years ago. The show becomes a success thanks to the "real looking dinosaurs and scenery" which cost nothing.
