The closing credits say this episode was animated by Wang Film Productions/Fil-Cartoons. However, this is most likely an erroneous miscredit, as the episode appears to have actually been animated by Akom Productions.
Silas Wonder and His two henchmen were enemies in Level 2 of the SNES game, "Buster Busts Loose".
Gogo (a la Edward G. Robinson): Shh! Now, listen up, see? We're busting out of this joint at midnight, see? I swiped a spoon from the mess hall. We're gonna dig Our way out of here, You got it? Yeah.
Sphinx: (Sobs.) These cages are made of steel. We'll never get away from that unwonderful Wonder. (Gogo is back to normal but still retains His Edward G. Robinson voice.)
Gogo: Ah, well, You gotta have a plan, see?
Gogo (A la Peter Lorre): If that's enjoyment, I'll have pain on rye, and hold the mayo. Mm-hmm.
Gogo: (In Deep Voice) Danger, Will Robinson, danger! (In Normal Voice) I knew Silas Wonder would be back. (In Deep Voice) Now's My chance.
Gogo: No Problem. (Turns off Tv screen with a remote.)
Plucky: Give Me that! (Turns on Tv screen.)
(The Ringmaster falls in a cage and is running scared of the Devil.)
Devil: Now, My collection is complete. Ha ha ha ha ha ha ha ha ha ha ha ha!
Buster: You know there's nothin' like an ending with a little heart.
(A little heart runs by)
Little Heart: Gee, thanks.
This is a Gogo Dodo episode.
Credit Gag: Gogo appears, says "It's been Surreal", pulls out a remote, and turns the TV off.
