Mermin Volume 2: The Big Catch

Despite Pete and the gang's efforts to keep the fish-boy Mermin from
making waves in their small town, he can't help but stick out! An amateur
team of paranormal investigators has their sights on Mermin, and they think
he's their chance to make it big! Meanwhile, Benni, Mermin's round
aquatic companion, is ready to spill the beans about their lives in the
underwater kingdom of Mer, but perhaps things aren't as simple as he
says...
