While at Walden Commune, Zonker spent most of his time watching TV, getting high, and swimming around in a minuscule body of water called "Walden Puddle", which he considered to be a sacred and holy place. In his early years in the strip, Zonker had the ability to talk to plants. (Mike also talked to the plants during Zonker's stint as Lieutenant Governor of American Samoa.) In later stories, Zonker appeared to lose this ability, but it has sprung back up occasionally, and he has been seen conversing with a marijuana plant, and a scrawny Christmas tree in recent years. Other than these few exceptions, this power seems to have left him, and he misses it terribly. When wondering out loud why he had it in the first place, he was told "It was the drugs, man". Ironically, it was a plant that informed him of this.
