Robotnik's PROMOTION Party

Robotnik caught Sonic and Tails, so he gives himself a "PR-R-R-R-ROMOTION!!!"

So, in order to celebrate, he throws a PR-R-R-R-ROMOTION party. But, Sonic and Tails manage to escape and wreck the show.

Again, I used my Sonic Mega Collection Plus instruction manual so I can draw Dr. Robotnik the AoSTH way.

I also drew some work from early original Sonic the Hedgehog boxart. If you can spot it and name the boxart I drew from (besides Dr. Robotnik's Mean Bean Machine), you win a request

NOTE: Even though I drew Dr. Robotnik posing as he is in the Dr. Robotnik's Mean Bean Machine cover, I drew him (along with everything else) entirely freehand. As I said before, I used my Sonic Mega Collection Plus instruction manual/back cover as a guide, which means if I traced from said manual/back cover, Dr. Robotnik will be very small due to how they printed the DRMBM in the manual/back cover cover. And I do not even own a copy of DRMBM (I don't even have a Sega Genesis). So this does not count as tracing, understand?
