Jamie Smart's Bunny vs. Monkey.
(Book)

"When Monkey is sent into space by a team of scientists, he thinks everything will be smooth sailing. But not everything goes according to plan, and soon Monkey's spaceship crash-lands in a forest, disrupting the peaceful atmosphere. Convinced that he has discovered a new world, power-mad (but mostly incompetent) Monkey claims the forest as his own and determines that all other animals must be banished, including his soon-to-be nemesis, Bunny. As Bunny gathers reinforcements and goes head-to-head with the gadget-obsessed Monkey, hilarious hijinks ensue"--Amazon.
