This series didn't have the 65 episode contract, that's why it ended with only 39 episodes.
Goof: When Daisy is following Huey, Dewey and Louie out of their cell and they're followed by Donald and the guard (who's trying his best to restrain him while being dragged), she is wearing her pink dress. But after the ducks enter another room, she is back to wearing her light pink sweater and steel pink skirt (as seen earlier in the same episode).
Dewey says Donald is the only uncle they've got, which is not true, they must have forgotten about their Uncle Scrooge back when they stayed with him for a while in DuckTales.
Police Officer sort of look like Lucky from another Disney show Bonkers.
The Pugduddies are being sold for $20.
Pugduddies look like a cross between a Beaver and a Duck.
While Huey was playing the organ, sometimes all the keys are in white, sometimes normal and sometimes there are no keys!
When the police called Donald, they said they'd be there in an hour. However, they appear shortly after Donald and The Claw become friends.
The G.I Monster would later appear in "Snow Way Out", not in this episode yet. Captain Jack is the first one where we wonder if it is real or not.
Just like the G.I Monster, Captain Jack seems to be more than just Donald's imagination. He is eavesdropping at the police station, knocking on the door, and even helping Donald out in the car chase.
It makes you wonder if he is real or not.
Huey and Dewey are sitting in the right chairs in the poodle scene when the host is talking to them, but the letters are switched. Louie is the only one done right.
The word selfless is used a whole lot in this episode.
Donald climbing to safety in the spaceshuttle is being seen again in the themesong
Although Kent is right about Donald being egocentric and selfish, he is being hypocritical because he himself is also selfish and egocentric.
The name of the Hospital in this episode is Duckburg Medical Plaza.
The Mad Doctor names the germs, they are: Tony, Mel, Jim, Ben, and Don.
Apparently, germs can be created by trying to catch a cold by using lots of fans and putting your feet in a bucket of water using blocks of ice. Or so the writers show us, it is the plan of the Mad Doctor.
Why would Donald ground all three boys while Louie caused the volcano to explode? This proves Donald isn't one to reason with and he has a very short fuse.
Ironically, the bed where Donald sits on, has a picture of a duck on the wall above him, in the Doctor's room.
The doctor has a dartboard in his room, assuming he plays darts.
