We’re talking skyscraper here. Emily Elizabeth would need to install an elevator in his dog house to get to the top. If the ray was super intense we could just cancel the space program. Astronauts could just climb up Clifford’s back to the international space station.
When I first read this question it made me wonder what would happen if Clifford was hit by a car. Demented I know. I am fairly certain that the big red dog would knock whatever car he had a run in with into next week!
