Grumble Meter Cake

OCCASION: Birthday
FLAVOR: Mint Chocolate

My friends Dillon, Julie, and I have a running joke about people being 'grumbly'.

grumbly [gruhm' blee] adj: bitterness, grumpiness, or snappy behavior typically associated with sleep deprivation and/or hunger.

Dillon often used this word to describe my best friend Julie, who is very pleasant and sweet, but often would get a tad irritated at lunch time (which coincided with her waking up from her 1st-3rd period nap). Julie isn't the only grumbly person out there though; everyone has his/her grumbly moments, some people just don't get called out about them. Dillon has grumbly moments, our teachers have grumbly moments, strangers have them...I don't have them, of course, because sweet cupcake bakers don't ever get grumbly. :) Anyways, so I made this cake for Dillon's 18th birthday to follow up on our inside joke--it's a meter to measure a person's grumblyness. Try to stay in the green zone, please.
