Synopsis

Polly was seized by the two royals, managing just before to send a call for help to Underdog. Witnessing his beloved taken captive by the aliens, Shoeshine Boy dashed into a phone booth and transformed into Underdog. The villains, Bric and Brac, then employed their malevolent space magic, transmuting our hero into a basketball, which was promptly sent bouncing across a children’s playing field.
