So I don’t speak Italian. I ask for your forgiveness as I offer the google translate version of what Mario is saying:

Panel 2: Itsa Me! Mario! My spaceship is slow and noisy! (I feel like that is saying “And-a noisy” but I have no idea)

Panel 4: It looks slippery… example: BURPA BURPA BURPA

Panel 6: Shit! (I’m so proud of myself for not needing translate for that obvious one. I’m not a total idiot.)

Panel 7: You were right. But now I’m in last place!

Panel 9: Eat turtle shit and die, BASTARDS!

Panel 10: What the hell?
