Buddy, in case you don't know him, was the second Looney Tunes star. First there was Bosko, but his creators moved to MGM, so Leon Schlesinger rehired some of the animators and they created this rather boring character. Over about two years, the Termite Terrace crowd sent Buddy through a series of random adventures, apparently never giving him much of a personality. "Buddy's Day Out" has Buddy and Cookie, plus their baby Elmer (an early Fudd, perhaps?), going on a picnic.
It's no surprise that Buddy didn't last very long. With "I Haven't Got a Hat" in 1935, Leon Schlesinger Productions debuted Porky Pig and thus began the Looney Tunes as we know them today. During the Buddy period, the Merrie Melodies - featuring miscellaneous characters - were apparently much more memorable than the Looney Tunes. This one is good as a historical reference.
