The Gremlins is an American film released in 1984 that was a worldwide success. It features seemingly docile little creatures that must be guarded with care.
There are 3 rules to follow if you want to avoid trouble:
-No exposure to light, especially sunlight which would kill him,
-Do not get it wet, otherwise it will multiply,
-Don't give him food after midnight, to avoid that he turns into a nasty Gremlin...
