First we have Donald's ducks... Donald owns a family of pet ducks
The second issue I have is with the clubhouse itself:
I dunno, maybe I'm the sick one here, but just try to imagine a similar structure built with pieces of Donald or Goofy... Doesn't seem so innocent now, does it?
I wasn't going to do this, but my sister absolutely insisted that I provide visual aids for the images I invoked above. She's to blame for me drawing this. That said...
The Donald Duck and Goofy Clubhouses:
I apologize profusely to everyone for the existence of this. I'm going to go sit in the corner now.
