Wippback was a very minor character who served on Reynard Chopsnout's ship, the Greenhawk. Practically nothing is known about him/her, besides that s/he is a rat. S/he invented a plan, opposed by Chopsnout, that involved ambushing the beasts on shore. However, the beasts on shore (Luke the Warrior and Vurg) knew they were coming and had prepared a counter-ambush for this eventuality. Wippback was killed, along with the rest of the crew of the Greenhawk.
