1) LOVE the pic!
2) Wis seems a little high - any particular reason for the 14?
3) Why a special mechanism for Drop damage vs. just using DR? Say DR5/piercing during a Drop?
4) Are koalas really that big? I thought they were only 3-4 feet tall.
5) Otherwise, seems very well balanced. Another fine creature brought to you by the twisted mind of the Vorpal Tribble.
