What means
The Aquarius used it as a fixed tile for the playable frog. A 1983 Phrogger screen capture shows it during play. The Aquarius stored small character shapes in a built-in set and assembled them into game scenes instead of drawing flexible pixel images. This glyph supplied the frog in that screen.
What does it mean when someone sends it?
By itself, it shows a frog; the message supplies the reason. In retro-computing or Frogger talk, it can point to the Aquarius game character. Without that cue, read it as a frog image and use the surrounding words to understand why the sender chose it.
Playful, nostalgic game art when the reader knows the reference.
