Giga Thomas "Pen" (ギガトーマス “ペン”, Giga Thomas "Pen"^?) is the boss of Robotnik Winter Zone in Sonic Triple Trouble.

BattleEdit

The early part of Robotnik Winter Zone Act 3 requires the player to climb up the slopes of an icy hill, all the while being forced to dodge skating bomb-penguin Badniks descending from the summit. At the top, the player finally finds the source of this stream of robots: Giga Thomas "Pen", a giant flying penguin head that spits the smaller Badniks at Sonic from the depths of its cavernous maw. Landing 8 hits will cause the boss' thrusters to fail, and he spirals away into the depths of a huge pit.
