Hawaiian Punch once had a mascot called Punchy the Puncher who punched everything he saw.

His catchphrase should have been “buy this...or else.” The animated character was introduced in February 1962 on a commercial for the drink. “Punchy” punched everything he caught sight of; horses, meatloaves, and yes, even kindergartners. The character was created by artist Martin Mandelblatt, animated by Jan Svochak, and voiced by Len Maxwell. 

Punchy’s actual catchphrase was “How about some nice Hawaiian Punch?”and would be followed by Punchy literally punching his next unsuspecting victim. The victim of Punchy’s “shenanigans” in the initial commercials was a tourist character named Opie (sometimes referred to as Oaf). After Punchy said his catchphrase, Opie would reply with “sure,” only to get punched in the face. 

Punchy has evolved from the original design to the character seen today. He has refrained from punching things since 1990, but had a brief relapse in a 2003 advertisement that saw Punchy knocking people into walls at a fun house.
