Captain Olimar's Journal
"I wonder what's become of the creature this shell was defending. Enigmas like this always make me curious. Was it tasty? Maybe I should find one and give it a taste? All in the name of science and exploration, of course..."

Sales Pitch
"A twisted shell whose surface is covered in spikes. The durable housing protects a meal that is said to define deliciousness. (Where the meal went is known only to Captain Olimar's crew.)"
