broadcasts). Synopsis The comic adventures of two unlikely best friends. Big and Small return from the fair with a balloon each. They love their balloons and play with them all over the house, bouncing around happily. They decide to show the balloons their garden - the frogs, the junk pile, the apple tree... While outside, however, Small accidentally lets go of his balloon and it starts to float away. Big makes a grab for Small's balloon - he manages to save Small's balloon but accidentally lets his own loose. They watch Big's balloon float up and away in the sky... They take the remaining balloon inside for safety. But inside the house the balloon is almost lost through an open window. Big and Small decide they have to keep an eye on the balloon at all times, even during the night. They struggle to stay awake, however, and are soon asleep. When they wake in the morning Big and Small can't, at first, see the balloon - but then notice it slowly sinking down to the floor... Small is shocked and runs over to give the balloon a hug - accidentally causing the remaining air to be crushed out. Both are sad when looking at the deflated balloon, although Big says that balloons are like flowers: they are never around forever. When thinking of the balloon Big and Small are reminded of the blue ball they used to play with in the garden, too - and they rush off to play with the ball again.
