limes?

[pvemily1012.livejournal.com]

i need a bit of help/advice on how to go about making something..
i have an inside joke with my friend involving a superhero lime..and i wanted to make her a stuffed limeman out of felt.. but i have no idea how i'd make it the shape of the lime of anything.
and adding arms and legs. it seems like a bit of a challange..
is there any sort of lime pattern i could use to sew this thing?
and how would you suggest going about this..
i hope i'm not breaking any rules with this post.
thanks =]
peace out.
