I hit a random Roku channel on my tv and a movie in spanish showed up where kids are the protagonists. There is an asian villain (bald and dressed like a monk) who I think is named Cobra. The villain also has long black nails on his index and thumb.

They are fighting for a blue stone and a medallion possibly. The kids know martial arts and the main kid is a caucasion kid with brown hair.

The villain scratches himself with his nail (which may be poisoned) and falls into a vortex of some sort.

The main character is named Billy if I heard it right.

More info:

  • The movie is most likely in English and I just saw a Spanish dub.

  • The kids dig up some medallion due to a time travel thing and place a blue stone in it. This is used to take them home.

  • Pineapples are used somehow to help them escape a prison, I don't know how.

  • The story is narrated,as a guy is telling a story to his kids.

  • jman - as I remember, military slang for a hand grenade is "pineapple", so if the charactersw were really throwing exploding pineapples instead of hand grenades, its obvious where the writer got the idea of exploding pineapples from.. Apr 2, 2017 at 18:25
  • I had to look it up, but Cobra Commander never used exploding pineapples in a nefarious plot to make a volcano erupt - which was my first thought.

1 Answer 1


This is the 2013 film 'The Lost Medallion: The Adventures of Billy Stone'.

The review on wikipedia mentions a medallion, a time-travel theme, a main protagonist called Billy (obvs) and a villain named Cobra. A quick glance at the video below shows a scene where the kids throw explosive pineapples at the villain.

The goons discover them and chase them through the city. After a bit, the kids, thinking they have lost the men, head back to Billy's home, only to find that the goons have arrived before them and tied up Billy's dad. Billy yells "I wish this whole mess had never happened!" and the medallion sends both Billy and Allie back in time (200 years).


The wise man tells them that they must complete tasks, and in return he will teach them how to defeat Cobra, the enemy that attacked the camp, and the evil warlord who keeps the natives in terror, and get the medallion back. The kids travel to the island of Cobra. On the beach of Cobra's island, Faleaka is shot by an arrow and killed.

  • That would be my guess as well. As I recall the pineapples exploded (I was perhaps nine at the time... so it's been a while though.)
