add crunchy worms to the june event shop

unlike several other important breeding items, like lion scrotums and buffalo scrotums, crunchy worms appear only once per year in the october shop.

with an increase in popularity of cloning lions, i believe another way to get crunchy worms is desperately needed!

i would like to suggest adding them to the june event shop. this would be a good balance point with october to allow players an opportunity to stock back up on these important items!

thanks for your consideration! :)
