Wyatt Burp orange soda was a type of orange soda that was presumably popular in 1965 in Danville, but was discontinued in the 1970s as a result of it's destructive effect on the environment.
The soda seems to have a wrap-around label on the cans that's mostly blue, but has a graphic of a rising orange slice, with the word "ORANGE" written over it. It also has a white stripe and an orange stripe at the top. Nearing the bottom, it has a brighter orange stripe than the shade of orange in the graphic next to it.
It was presumably first sold in the 1960s. In 1965, Dr. Heinz Doofenshmirtz, having journeyed back in time on the maiden voyage of his time machine, along with Perry the Platypus, Balthazar Cavendish, Vinnie Dakota, and Orton Mahlson, partially made the journey for the reason of obtaining this soda, although Cavendish later revealed this to be part of the reason that he was angry with Doofenshmirtz.
In the 1970s, the soda was discontinued because it was known to cause serious harm to the environment (such as severe chemical "burns" to vegetation).
Decades later, on the Island of Lost Dakotas, the time travel-created clones of Dakota manufactured Wyatt Burp orange soda for themselves, and subsequently offered them to Doofenshmirtz, Dakota, Cavendish and Mahlson when they crashed on the island.
- The soda seems to be made in both bottles and cans. The fact that the Wyatt Burp company logo has a bottle of the soda in it, and that Doofenshmirtz was seen carrying them while running to the time machine in 1965, would seem to show that the bottles existed as an original form of the soda. The cans, however, have only been seen as manufactured by the time travel-created clones of Dakota, doesn't negate the idea that the Dakota clones were the original inventors of this size (although this is likely false).
- The fact that the time travel-created clones of Vinnie Dakota made and presumably enjoyed the beverage too, suggests that Dakota may have enjoyed the beverage as much as Doofenshmirtz did.
