Martha is actually from Lexicon.
This is what allows her to talk - being from the planet of vocabulary, she just need a little trigger (alphabet soup) in order to be able to use it. For all we know, Captain Huggy Face might be able to speak English when he eats alphabet soup as well.- Jossed. We meet her biological mother (who's not an alien) in "Martha's Thanksgiving" and find out she was born in an alleyway on Earth. Though alternatively...
Martha's dad is from Lexicon.
Think about it. Whenever she mentions her family, she never mentions her dad and he's never seen in flashbacks. He didn't come to her family reunion. Maybe he's from Lexicon, went to Earth, mated with an Earth dog, went back to Lexicon and his DNA is what made Martha like that. Does this mean her siblings would be able to talk if they ate alphabet soup? Who knows.- Well, we do know the planet has chimpanzees, so it wouldn't be weird to expect it to have dogs too.
Where's Wagstaff City?
Here are some of my guesses!- Flagstaff, Arizona. The city's name is an obvious play on the real city's name. Furthermore, it does snow in Wagstaff City, and in Flagstaff in real life. Even many people do take Martha Speaks to be taking place in Arizona. Pluto is also heavily mentioned throughout the show, and it was discovered by Clyde Tombaugh from the Lowell Observatory in real-life Flagstaff. T.D. Kennelly playing Pluto may allude to the city being in Arizona. "Dogs in Space/Dogs from Space" also shows spacecraft returning to Earth in the direction of Arizona.
- Flagstaff, Maine. This is currently a ghost town (see also the Danny Phantom theory above), however the Martha Speaks universe may have Flagstaff in Maine as lively. The PBS summary of "Martha in the Hold" states that Martha's family is going west on their vacation, and in the episode, they go to Montana. Montana is north, not west, of Arizona, but west of Maine. Wagstaff City also has a lake that is large enough to contain blue whales and have ferries going across it. Flagstaff in real life lacks this - but Flagstaff, Maine has a lake nearby even named after it. Furthermore, in the two-part "Martha in the White House" episode, the children are brought to the White House and ride in the President's car. Washington, D.C. is a huge, long drive from Arizona.
- Close to the United States-Canada border - close enough that Canadian culture is a major influence on the town. Daniel is Canadian, and hockey is a major sport in Wagstaff City; Helen plays it. Moosejaw is also mentioned in an episode.
OG is actually a younger version of Doc Brown
- Messy hair, wacky personality, likes to invent things, you do the math. OG even invents a time machine in one episode. Clearly, the Doc, at some point, sent himself into the future as a young man, either by accident or on purpose, met Janice and decided to marry her and stay there. That would explain why C.K., who's supposed to be his brother, is so much older than him, because he's the age that he should be, while OG isn't.
- Alternately, OG is the son of the Doc and just inherited some of his father's traits.
Billy Collins's dog gained his ability to read from food.
"Billy Collins Speaks" reveals that a poet named Billy Collins has a dog who helps him with his poetry, and this dog can't talk, but he can read and write (unlike Martha, for whom the reverse is true). Perhaps a certain food made him this way, just like Martha and her alphabet soup. Nelson did use the zipline seen at the end of "Martha Takes the Cake", but he didn't build it.
Explaining both why it was there and what Nelson actually did — he didn't build it like T.D. thought (he couldn't have, since he doesn't have thumbs). It actually belonged to one of the Boxwoods. However, when Nelson saw it, he did use it to access the basement and thus he did indeed frame Martha with it. If this is true, then T.D. was half-right and half-wrong. Ronald's friend Reginald and his brother Simon are Jewish.
Hence their surname, Steinglass. All the various Marthas are connected.
One odd thing about this show is that it averts the One-Steve Limit with the name Martha a lot — it's the name of the protagonist, Mrs. Parkington's great-aunt, another dog, and the founder of Wagstaff City. Perhaps the great-aunt was the founder of Wagstaff City, and both dogs are named after her. When they grow up, the kid characters will have the following jobs:
- Helen - Professional painter, due to her enjoyment of painting seen in several episodes.
- T.D. - Either a comic book writer or an inventor like his father, due to being a Mr. Imagination.
- Truman - College professor, due to his nerdiness.
- Alice - Professional athlete, due to being a Lovable Jock.
- Carolina - CEO of a fashion company, due to being both bossy and The Fashionista.
- Tiffany - CEO of a rival fashion company, which fits the rivalry she has with Carolina in the present.
- Milo - Owner of a summer camp, because he's a Nature Lover. The "five-athlon" invented in "Milo Goes for Gold" would be one of the activities at the camp.
- Jake - Animal shelter worker, because he seems to be an Animal Lover, commonly hanging out with the dogs.
- Ronald - Journalist, due to his Ronald Report paper.
- Reginald - Also a college professor (owing to his habit of speaking in Sesquipedalian Loquaciousness), possibly even teaching at the same college Truman will teach at.
- C.D. - Also an animal shelter worker, since he's also an animal lover.
- Stanley - Movie director, due to his love of watching movies.
