sound loop script help

[Mine Turtle]

yo, umm. im making a script, where you wake up (taken care of) but then you are freezing, and have to find clothes. now, i need to make a sound loop, and every time the sound is gonna be played, the script has to choose randomly between a selection of 6 sounds to be played. the loop has to play the sounds randomly every 2 seconds

(ive looked in the wiki, but im very new to scripting, and a friend of mine told me this was a very complicated thing to do)

thanks in advance! ^^
