Professor Kompressor visits Walter's family, offering a remedy for the
dog's digestive disorder: special food that must be mixed in his
Kompressatron. Unfortunately, the professor's cure doesn't work, so
Father has to take matters into his own hands. Father's combination of
ingredients has a strange effect on the pooch--Walter blows up like a
balloon and floats out the window! Just when it looks as though Walter's
paws may never touch earth again, he encounters a flock of butterflies
in distress. Only he has the hot air that can save them from an icy
death. Once he lets it rip, Walter's flying days are over (or are
they?).
Plenty of laughs and cheers will arise from this story that takes walter
to new heights.
