I had a Leprechaun in 1st thru 8th, Wolf from 9th thru 12th grade, Artie the Artichoke my college Freshman and sophomore, and finally Sparky the Sun Devil college junior and senior year.
The Artichoke mascot was because the students were forced to choose a mascot and did it to spite the administration of Scottsdale Community College.
I have a plush Artie the Artichoke magnet on my fridge that is pretty neat.
