Barney and the Backyard Gang: Three Wishes 1988 on netflix

The Backyard Gang are bored on a Saturday with nothing to do. That is, until they use their imaginations to bring Barney to life. When they tell Barney their problem, he acts like a genie and gives them three wishes to go anywhere they would want to go in their imagination. Using their imaginations, they go to places like a fun park, the Moon in outer space, and even a fun-filled animal farm. But when Barney leaves, the kids learn from Mom that “friends are forever, whenever they’re make-believe”.
