Sisi Truck

Sisi Truck (シシトラック) is the sub-boss of Turbo Man's stage in Mega Man 7. It is a giant semi-trailer truck that Mega Man runs on back of before confronting the front. It fires Sisi Rockets, which are missiles that look like it. Mega Man can't proceed until it is destroyed (and when it is destroyed, it has a silly look on its face and some of its teeth are missing).

Trivia

 * Sisi Truck is based on the Shishi lion statue. Sisi Roll and two bosses from Megaman ZX Advent are also based on this.
 * If you look on its license plate you'll find "Sisi," hence the name.
