Are you ready for this?
Ok.
First, I'd distract it with the enticing body of a dead raccoon. Then, I'll run to the nearest town and hitch hike up to an air port. I'll fly to Australia, grab a kangaroo and head to Thailand where I will pay for the kangaroo to take Muy Thai lessons. After it has achieved mastery of this martial art, I'll find out where Ken and Ryu are hanging out and have them all train together.
After my kangaroo has successfully obliterated Ken and Ryu I will then travel to wherever the hell it was I left that killer rabbit. I'll invite the rabbit over for tea and biscuits. Once the rabbit has arrived, I'll shoot it and allow the kangaroo to beat the lifeless animal into the ground.
