Darkwing Duck:
*The 29th Page* (Rubber Room);
*Springtime for the Iguana* (the photo with Roderick Lizard);
*Do Toons Dream of Animated Sheep?* (Bonkers' dream);
*Of Mice and Menace* (on TV).
Mickey Mouse:
*I Ought to Be in Toons* (his name is never pronounced and he cannot be seen, but we hear his voice).

Marsupilami:
*The 29th Page* (Rubber Room, together with Darkwing).
Mad Hatter & March Hare:
They play a major role in the series, therefore I even included them into the
Cast list. However, since these two characters came from *Alice in Wonderland*, they can be considered guests.
Professor Ludwig von Drake:
As well as the above-mentioned couple, this scientist (originally created for *Duck Tales*; according to
some sources, he is Donald Duck's uncle) had more than just a cameo appearance in the show.
Ferdinand the Bull:
All oxen seem the same to me, but the one in *Do Toons Dream of Animated Sheep?* resembles Ferdinand.

*Springtime for the Iguana* (one of Roderick's photos).

*The 29
th Page* (one of them is Al Vermin's client);

Pluto:
*Bonkers in Space* (the planet of the same name is Pluto-shaped).
Teenage Mutant Ninja Turtles:
In *Tokyo Bonkers* there are four Ninja Kitties named after famous musicians (the Ninja Turtles were named after artists). Z-Bot, the main villain, is a pink brain who needs a mechanic body (a reference to Krang).
