There isn’t a whole lot to be said about the catcupcakes as they are newly developed characters of the channel. One could say they are the purest representation of personality types that are not always appreciated. To this day, only Nilla & Punkin currently have a human form.
The original concept in mind with the catcupcakes was to have ranks for viewers of the channel. The more you watched the channel, the more your rank increased, the further up the cake line you go. Now these little cuties have thier own personalities and character traits!
