Buck Wondrous cared about his carbon footprint. As such, his adventures were somewhat limited, at least for the moment, and as regards to space. With his new Time Trebuchet, he was no longer limited in the realm of time. That was because his Time Trebuchet was solar powered. It also had an attachment to gather wind energy, should it be a cloudy day.
The first few times Buck tried out his new time machine, things went terribly bad. On his first excursion, he forgot to punch in “B.C.”, so when he went to pay a visit to the dinosaurs, he instead wound up far into the future, and was in way over his head.
That was when he thanked God, and his parents, for sending him to Camp Thunderbird, lo those many years ago, because, had he not been able to swim, he would not have survived the future, because, as far as he could tell, the earth, or at least Charlotte, was very much underwater.
