FLIC

FLIC, also known by the extension *.FLC or *.FLI, is an animation file format developed by Autodesk. It is similar to an animated GIF but was used frequently in video games throughout the 1990s (as opposed to GIF which was largely adopted by web standards).

In LEGO Island
FLIC is one of two video/animation file types used in LEGO Island, the other being Smacker. Since it is similar to GIF, it is largely used for GIF-like purposes such as:
 * The small background videos in the building stages
 * Registration book animations
