Is he gonna sing in the rain?

Nah, but people might have their waistlines grow if they approach them, he's got some lipomancy magic he uses...for pranking purposes.

I guess I might keep my distance although I wouldn't mind having my butt fattened up

You may not have an idea for this picture title, but what a picture it is! First and foremost, look at that rain coming on down and the puddles that have formed! Its all nice and moist now!
But look how huge that guy is! Its wonderful to view this interesting plant from above so we can see how immense their rear and belly is all at once! Including the fat arms and back too! How cute!

"Cute" may not be the right word. He can be quite a mischievous person I tell you, especially with his lipomancy magic.

He's just simply enjoying his time there, fattening up as he heads back home. I wonder if he'll meet the next victim for his prank antics though?

Oh my! That's something that's humongously mischievous to toy around with! Beware all who might be in his sights to play around with their fat!
