Rowlet's Possible Father

Rowlet's Possible Father was a concept introduced in "Time Flies" when Toucan Sam questioned how Rowlet could impossibly be his biological son, mentioning his wife shouldn't have taken a job at Hooter's as it lead to her having a possible affair with an owl.

TRIVIA
 * Although not really speculated, this unnamed character was most likely an owl for two reasons... Reason 1 being that Rowlet is himself an owl and Reason 2 being Hooters implied to be an owl 'hangout'.
