Marceline’s music are not what the Ice King loves the most. Avoid his ice blast attacks and defend Finn and Jake from the penguins attacks. Another time for more adventure near the frozen kingdom, where our vampire character loves to play her guitar and perform some post-apocalypse rock songs. Using the Mouse, make her fly or float and collect the precious gems floating in the mid-air, while she hits the targets, the little penguins, at the same time when she thrusts herself up. Let them enjoy the music without being attacked and hurt.
