This was a Nintendo ds game I had as a kid. Not a 3ds game! It started out with this cute little blob character and I believe the other little blob/character things get taken away. Throughout the game you unlock other characters and save them there was even a little dojo in the game. You had to also go into battle. You'd shoot different weapons like knives, daggers, and even holy water at the other ship thingy. You eventually had to get to the other side and break these light bulb things and get to the heart.
