In unusual but true stories this week, we have guinea pig-flavored ice cream, a puppy in a wheelchair traveling with his owner, an autonomous bus in Germany, and astronauts experiencing life on Mars.

All the odd and interesting anecdotes from around the world are here in our review.

Guinea pig-flavored ice cream

It can't be easy for people who think of guinea pigs as cute pets to learn that guinea pig-flavored ice cream exists in Ecuador.

In Ecuador, people typically cook guinea pigs with salt and serve them with potatoes and peanut sauce. But Maria del Carmen Pilapana is taking things to gastronomic level, serving guinea pigs as a cold dessert.

"My family and my husband thought I was crazy. They didn't think anyone would like these ice creams, but now they're our main products," said Pilapana. She began attending free training courses for entrepreneurs and decided to do something innovative about half a year ago.

Ants, cicadas and worms are used to make some desserts, often chocolate-infused ones, in parts of Latin America. But incorporating such ingredients - guinea pigs included - into ice cream is unusual.

Maria now has new flavors in mind like crab, chicken and pork.
