Remember back in the 80's when Sugar Bear used his cereal like Popeye would power up with spinach? He didn't need to do that in the 60's, when he had his own backup feature on Linus the Lionhearted. While it seemed as though Sugar was more interested in playing his banjo all the day long, he really did have a girlfriend in Leslie Bear, who unfortunately wasn't around by the time Post introduced Super Sugar Crisp and turned Sugar into Super Bear.
In "Head Over Heels", it takes Leslie being in distress for Sugar to take his mind off his banjo, and ultimately settle up with Mervyn the Magician. Voice actor Gerry Matthews based his characterization of Sugar on Dean Martin, which wouldn't exactly make Lovable Truly, for example, to be Post's answer to Jerry Lewis, now, would it? I digress.......
Yeah, Sugar might've been a bit slow on the uptake, but when you're in love.......!
