Sure, here's the implementation of a simple snake game where the snake grows bigger by eating coconuts within a cage. The game is designed to be played on a smartphone using pictograms.

Please note that you need to have a coconut image named "emozi_all/coconut.png" in the same directory as the HTML file for the coconut pictogram to be displayed correctly.
