There is a reference to the arcade game "Shinobi
" : the 'Hiyaaa' sound that Ben and Andy exclaim after detonating a superbomb is the same sound as the Shinobi ninja magic sound. Also, 2 of the 4 superbombs also appear in Shinobi. Look closely, the electricity bomb and the whirlwind with homing sickles bomb are here too.
At the end of scene 2 act. 2. There is a machine that produces electrical sparks. On top of the machine can be read : 's-4635 system24'. This is a reference to the arcade board this game runs on.
