There are many words to qualify Fi but I'll just stick with the nice and basic
ones cause it's his birthday.馃槒
If you like really cool people, It won't be hard liking Fi. A very approachable brainy simple person in a universe of his own.
If there is anything he can do wrong in, it is definitely not smiling.
A word bender in his own write (you see what i there? Huh?).
He eats too much food! Or just likes taking too many pictures of them... I'm not sure.. And i doubt he can really cook sef馃槖
He works hard yet the Fun in Funmibi isn't there just sitting pretty
Happy birthday 
Blessings on blessings on blessings
