Woodchucks

Woodchucks are mischievous yet devious rodents that first appear in Signature Deer World in 1996, where they throw lumber and destroy things for fun, and in Signature Deer 4 in 1997, where they try to throw health hearts in the water in Water Ruins, which are needed to regain health. Mr. Buck fortunately can easily kill them.

Description
Even though they are not enemies of Mr. Buck and do not work for King Coyote or any villain in the series in any way, they are considerably troublemakers, as in Signature Deer 4, where they steal health hearts to prevent you from getting another hit point, and in Signature Deer World, where they throw lumber wood at things.

They are also incredibly impolite and laugh at Mr. Buck when they hit him in Signature Deer World, and call him "wedged deer" in Signature Deer 4, alongside "bigheaded deer", "largemouthed freak", "shirtless guy", "killer's pet", and even "deer hopper" as a form of taunting him, which can be a very annoying and aggravating situation to those who are easily angered, as they will continuously say them every 2 to 5 seconds.

Furthermore, they can also be very annoying, especially in Signature Deer 4, where they constantly try to jump on him to annoy him nonstop, as well as purposely mocking his movements while laughing at him, throwing objects (pinecones, rocks, or pieces of wood) at him, and in one level, even force him to stand on a ball as he struggles to keep balance on it and laugh hard as he tries to keep his balance. See Water Ruins Level 4: Try Balancing for more description on this.
