Plankton -
(Interupting) Never that's completely idiotic

Spongebob - Here let me help you!
F is for friends who do stuff together
U is for you and me

Plankton -
N is for anywhere and anytime at all!

All - Down here in the deep blue sea

Plankton -

I don't understand this
I feel all tingley inside

Spongebob - No thats how your supposed to feel!

Plankton -
Well I like it!
Let's do it again!

Spongebob & Plankton -
(Spongebob) OKAY!
F is for frolic through all the flowers
U is for ukelela
N is for nose picking chewing gum and sand licking,
here with my best buddy!

(Laughter in melody)
