Professor Alphonse is a noted scientist who is heard in a "Sesame Street News" radio segment recorded for the Numbers computer game.

Kermit the Frog interviews the professor from the "Island That Time Ignored." Alphonse is among those studying the many interesting creatures that inhabit the island. He confirms to Kermit that the creatures he sees are in fact dinosaurs, specifically a One-osaurus, a Two-osaurus and a baby Three-osaurus.
