i like your honesty, so here is some free help.
1. First off, make your recording samples, while you are talking semi-slow. Sort of like Forest Gump, without the accent.
2. download Audacity and install it:

3. load your sound sample, and select all by hitting control-A
4.in Effect change the playback speed. basically twice the speed.
5. in Effect change the pitch. High C seems to be a good one for the worms voice.
with some trial and error, you should be able to "nail it". after a couple of trys.
