Mostly unintentionally, the LocoRoco are eaten by huge creatures and need to make their way through the creature and get out safely. Inside there are the usual things to find in levels like Pickories, Berries, Mojas and often Koona Mama. The tune 'Uwauwauwau' is heard when inside, except when inside Bonmucho where the tune 'Merure Merure' is played.
