Stone Doohickey

Stone Doohickeys are red statues that guard the boss doors in Wario World. They resemble tall, thin pillars with a crest of The Black Jewel on top. In each level, Wario needs to gather Red Diamonds to give to the Stone Doohickey. Once enough Red Diamonds were handed over, the Stone Doohickey would disappear, and Wario could fight the boss.
