Prince Marvin's Great Moment

Poor Prince Marvin, the Meek! His twin sister, Princess Gusty Ox may be
built like a battle ship but Marvin has always been a bit...physically
feeble. It's not surprising his sister bullies him. But, when his
father King Cudgel's best suits are ruined by mysterious globs of green
gloop, things get even worse. It seems that Harry the Hairy Green Giant
has caught a cold and the King orders Prince Marvin to sort him out. If
Prince Marvin can cure the giant and prove himself, his sister won't be
able to bully him any more. But first he needs a little help from
Crackle the court magician...This is the second laugh-a-minute
historical adventure in The Crunchbone Castle Chronicles.
