As described on Slimbox website (http://www.digitalia.be/software/slimbox), we don't need all mootools compents. So you can just download the required components. This will reduce the mooltools.js size to about 20kB (original 188 kB).

This file is only the optimized mootools.js file downloaded from http://www.mootools.net/download. You can also download it directly from the website.
