Or the Dudemeister, or El Duderino, if brevity's not your thing.
Dude first hatched on June 10, 2014 and died on June 16, 2014. He was on the iPhone Tamagotchi Life App. While the App didn't include gender or naming, I just thought of him as a boy by default and called him Dude. My phone ran out of memory for the app last night so I deleted him. He reached the adult stage and his final form was Maskutchi. This was the farthest that I'd been able to raise a Tama since getting my first one back in the 90s. I'm still a bit surprised by how attached I'd gotten to the little guy, and I still kinda miss him.
The Dude abides.
