These include electrical zappers and pounding elevators.
Robotnik plays an elevator/shell game with Sonic. Sonic must hit Robotnik's elevator to destroy him, while electric spark bombs fall around him. At the same time, he must keep his balance and avoid being crushed by the elevators. When Sonic destroys the Egg-O-Matic, Robotnik escapes by running away.
