I personally like the term 'GUWBR' (goober) better, but hey, that's just me. Moving on.
This is my first attempt at a WUBRG card. My first draft was JUST making use of the Amplify / Changeling meta, but I figured that was too little for too much, so I gave it Absorb 2. Probably still too little, but that's for you to decide.
Here's the way the Amplify / Changeling meta works; a card with Amplify gains +X/+X on summoning by revealing creature cards of the same type from your hand. Any number. Changeling effectively gives the card itself EVERY creature type possible simultaneously, meaning that you can reveal ANY creature card and it will gain +1/+1 from that creature. As it stands, the card is relatively powerful even without Changeling if you use it in a Sorcerer-heavy deck, starting with 4/4 and Absorb 2 (meaning you need to do 6 damage in total to destroy it). Oh, and as for the art - you might not be able to see it, but each of its eyes (5 of them) correlates to a different color of mana sans colorless.
