Rupert and the Clock Cuckoo is the 39th episode of Rupert and the 13th and final episode of Season 3.
- Mr. Bear
- Mrs. Bear
- Tick Tock the Cuckoo
- The Bird King
- The Bird Collector (or Bird Thief)
- When the cuckoo clock is making noise, the Bear family cover their ears against the noise. But it looks more like they are protecting their heads, then their ears. This is something that occurs more throughout the series.
- When Rupert is being lifted by his Jersey when the Bird Collector grabs him with his aircraft, his jersey is being pulled up, revealing Rupert's belly button. This is considered as a part of Rupert being an anthropomorphic bear, so half bear, half human. Normally when his belly is shown (Always for a very short time), the belly button isn't drawn/seen as a part of the mystery of what is bear and what is human to him. A other episode (Rupert and the Sun Bandit) does the complete opposite and reveals Rupert to be covered with Fur. Also an example is Bill Badger in Rupert and the Lamp who is in bad and doesn't seem to have fur or a belly button. Just white skin.
