I just added Rocko's last new striker "Sheila" for Rocko's next update. Do you remember her from the show? She made her minor appearance from "Wallaby on Wheels" episode.
The animation/coding starts where Rocko saw Sheila skating towards at her enemy, turns round back while she slashes with her tail at her enemy and skates back before Rocko waves at Sheila for saying "Bye-bye-bye....". Hopefully when I add and polish a little bit more few stuff to Rocko, I release his new update, along with R.O.B's beta.
