This a very small mod for cheerful gamers, than I :D
video HERE
Installing:
-make a backup/rename ->Sauerbraten/data/sounds.cfg;
Sauerbraten/packages/hud/items.png;
Sauerbraten/packages/models/projectiles/grenade (folder);

-unzip the ducky.zip package ito your Sauerbraten head directories
( if you did everything well, will overwrites nothing )

Any kind of license does not imply a file, but all new components freely utilizable. Maded by Me...

P.S.: Thanks LeChefRené for the fantastic ducky fonts!
