------------------- ABOUT ----------------------
--
-- In this adventure hero visits the fruit planet
-- to search for the missing part. However, a war
-- has broke out and hero has to take part or leave.

-- NOTES:
-- There is an ugly hack out there! I use 2 Captain Limes
-- One in human level and one in bot level
-- I want to have a Captain Lime in human level when the game
-- begins because in animation if the hog is in bot level skip
-- doesn't work - onPrecise() isn't triggered
-- Later I want the hog to take place in the battle in bot level
-- However if I use SetHogLevel I get an error: Engine bug: AI may break demos playing
-- So I have 2 hogs, one in bot level and one in hog level that I hide them
-- or restore them regarding the case
