Unbelievable!!
I can't even begin to say how great this series is! I loved Luigi's look when he [supposedly] pissed himself. Twice. XD
You did great on this episode, since you didn't cliffhang it. On previous episodes (e.g. episode 5), Mecha Sonic was coming to Yoshi Island to get the two Chaos Emeralds there. Then (suprise!) gotta wait until next installment. ;) It's ok, but it makes it feel like it's taking even longer for you to make the episode :p Now you have some time to kick back and take your time. But don't take forever, heheh... ^_^
Looking forward to forthcoming episodes, keep up the good work!
P.S. When Mario told Sonic to use the Star with him, I expected Fusion. The whole 10 seconds or so I was trying to figure out how the hell Mario + Sonic would look. XD
