XD When Rolf loses Wilfred in the Cow pasture, Rolf says, "Wilfred, where are you? Rolf is so sad! Like the the little eggplant Jimmy-boy, Rolf cries and cries!" And when you see Wilfred carrying the huge pile of Junk, you can see Victor!
At about part 7, Double D and Eddy get in a huge fight, and the conversation went something like this:
Double D: You and your various scams!
Eddy: Like you were picking daisies! Who built the thing? Double D: If you had listened to me, and not have pushed the red button...
All we know of the scam right now is that it involved a red button and had Rolf's stomach bitten off, Nazz was covered in a magic show box and Kevin and Johnny were just plain out beaten up!
