I'm not Ratty, but I'll barge in anyway - Slavic languages are synthetic with a light sprinkle of agglutination. If you want a true agglutination bonanza, you must aim a bit further to the north - i.e. Hungary.
Megatron, you could try a Slavic language. Then again, they don't have that many speakers, so they probably wouldn't be all that interesting apart from Russian maybe?
