Pig Head Statue
From the Super Mario Wiki
The Pig Head Statue is an object in the Game Boy Advance game Wario Land 4. It appears in the level Toy Block Tower, and some Puzzle Rooms. It is a grey, pig-faced statue fixed on the level's background wall, and it will open its mouth on regular intervals, spitting out fire which will smoulder on the ground below. If Wario touches or walks into the flames, he will transform into Flaming Wario, which will allow him to break Bonfire Blocks.
