Pink - Yellow overly attached creatures.

Friend is someone who accept your dark side. Bare with the over-limit of slothiness * its even a word * - overly attached . Someone who cheered  in times hardships and good time. 

Someone that I know, will be forever inside my episodes of life. 

Even they don't really meet the eyes, the heart is connected through invisible bond .

well. Those lines rushed into my mind when I saw this pink starfish - yellow living sponge with a square pants. 

They're Good Friends.
