Mayo recently explained in town center the circumstances of his return.

Mayo exclaims, "hey Paramedic!"
(Paramedic smiles and waves.)
Mayo exclaims, "Put me on the cover of TMN, I'm back from my grand journey!"
Paramedic asks, "a visit to the undiscovered country?"
Mayo says, "ahh well, if you haven't heard the story, it's a glorious one"
Mayo says, "not exactly an undiscovered country . . . see, a culcan ate me . . ."
Paramedic says, "Oh, that sounds painful"
Mayo says, "ahh well, it mostly just smelled bad"
Paramedic says, "Urgh."
Mayo says, "but I got the last laugh in the end because he couldn't digest me properly and washed up on a beach and died"
Paramedic asks, "So then you climbed out?"
Mayo says, "well, crawled . . ."
(Paramedic nods)
Mayo says, "my axe couldn't really hack anything to get out, not enough Atkus, you see"
Paramedic says, "That makes sense."
Mayo says, "and then luckily enough, Zephyrus (he was with me in the culcan, we were travelling together) had pilfered a coffee table"
Mayo says, "and so we used his stolen coffee table as a boat and paddled our way back to town"
Mayo asks, "glorious, eh?"
Paramedic says, "Yeah. I like the coffee table."
Mayo says, "the final time count was around 2 years and 5 months"
Mayo says, "give or take a month or two . . ."
Mayo says, "my adventures sadly haven't got me strong enough to pass 4th though =("
Mayo says, "I have thoomy matters to attend"
