Bullet Bill and Bill Blaster

Some drawings I did on the Bullet Bill and the Bill Blaster.
They are weapons featured in the Mario series.
They first appeared in Super Mario Bros. for the NES where they served as obstacles that Mario or Luigi must avoid in order to keep finding Peach and Bowser.
Bill Blasters are cannons used by the Koopa Troop to try to stall Mario and Luigi's progress on saving Princess Peach from Bowser.
Bullet Bills are small bullets fired from their Blasters at a very fast rate to try to kill Mario or Luigi.
Bill Blasters and Bullet Bills appear in many other games like Paper Mario, New Super Mario Bros. Wii, and Mario & Luigi: SuperStar Saga.
Bullet Bill and Bill Blaster respectfully belong to Nintendo.
