Added boards with built-in storage.  50% Trunk capacity and averaged the durability.
Fixes a metric pantload of spelling errors, bad grammar, incorrect punctuation, and malapropisms.

Seriously, who tried to take a thesaurus to the monster file? They
really should leave those long words to the folks who know what they
mean.
Changes 'jungle fowl' to 'junglefowl' and provides minor clarification.
Changed Mi-go'flexous' isn't a word, but 'flexuous' is!

To be honesty, Mi-go should be capitalized, since it's a proper noun (no
different from saying 'American' or 'English') that denotes a race of
sentient creatures.
Dropped comma, traded in for a period!
Fixed!
