A bunch of tiny, shiny, egg-shaped aliens called Spacers arrive at the jungle looking for a missing MacGuffin called a magic pearl, all while a poacher chick and her bumbling gorilla sidekick are out to catch as many animals as they can while looking for the Spacers and their pearls so they can please their boss, Mr. Stealmore, and get filthy rich. So David, along with his beagle Pips and a stray eagle chick David calls Sandy, set out to free the animals of the jungle, help the aliens find their pearls before Stealmore can and save the jungle from being destroyed.
This movie provides examples of:
- Alien Fair Folk: The Spacers note are the descendants of gnomes.
- All Animals Are Domesticated: All the animals in this movie, especially the eagles, display a friendly demeanor towards David and show no signs of aggressiveness in situations where a real life animal would, especially the eagles.
- Expository Theme Tune: "Hey, everybody, here comes Da-vey!"
- Filling the Silence: The original Polish version didn't contain David's narration; in the English dub, moments without David's narration are few and far in between.
- Good Costume Switch: The poacher changes from her hunting clothes to a dress and no hat. This somehow convinces David and the rest that she's really stopped being evil.
- HeelFace Turn: The poacher after being trapped in one of her own cages. Her sidekick does the same.
- Random Events Plot: A kid's family go to the jungle on vacation. Okay. Then he adopts a pet baby eagle and comes across some poachers. Sure, we can roll with that. Aliens show up to warn Davey that a corrupt corporate executive is going after a potent magical artifact. ...Wait, what.
- Starfish Aliens: The Spacers appear to be made of metallic cylindrical segments that float above each other.
- What Happened to the Mouse?: Where did all those bulldozers go after Stealmore is defeated?
