Materials are collectable objects that appear in Sonic Rush Adventure and the 3DS version of Sonic Lost World.

Tails picks up a book from Marine the Raccoon at the start of the game, which describes how to combine "metals and jewels" together to make boats. Over the course of the game, Tails uses Material to construct four principal watercraft, as well as other frighteningly complicated machines like the Magma Hurricane. It is up to Sonic and Blaze to collect as much Material as they can by clearing Acts and defeating bosses.
