This track isn't a mashup, but an intro I attempted to make for Dedede: Comin' At Ya, King Dedede's TV show in episode 49 of the Kirby: Right Back At Ya! anime.
lyrics
Dedede, that's the name you should know!
Dedede, he's the king of the show!
You'll holler and hoot, he'll give Kirby the boot, Dedede is the one!
He comes-a riiight, back at ya!
He comes-a riiight, back at ya!
Give it all that you've got, take your very best shot,
he'll send it right back at ya for suuuure, yeah!
"How can I help you King Dedede?"
"I need a monster to clobber that there Kirby!"
"That's what we do best at NME!"
"You'd better get it with a money back guarantee!"
Woooah, Dedede, saving the day!
Dedede, he's here to stay!
Don't be fooled by his size, you won't believe your eyes!
Dedede is the oooooone!
Comin' at Ya! (Yeah!)

I used the Kirby: Right Back At Ya! intro and the beginning and last parts of episode 49's Dedede: Comin' At Ya! to make this.
