(NOTE: This show used a lot of custom-recorded sound effects that are currently very hard to find on any commercially-available sound effects libraries (though some have since been released on the Soundelux Sound Effects Master Collection). It also uses a heavy amount of Warner Bros. sound effects, along with a limited selection of Hanna-Barbera sound effects, very much like the Looney Tunes and Merrie Melodies of the Warner Bros.-Seven Arts era.)
