Hamster & Gretel is an American animated superhero comedy television series created by Phineas and Ferb and Milo Murphy's Law co-creator Dan Povenmire that first aired on Disney Channel on August 12, 2022.

A 16-year-old boy named Kevin must work with his sister Gretel when she and their pet hamster are given superpowers by aliens and become a superhero duo dedicated to protecting their city.

As time goes by, Kevin becomes overprotective of Gretel, despite her now having superpowers, which she tends to overuse, in addition to being asked to keeping their powers a secret and only letting their cousin Fred in on it.

Gretel eventually convinces Kevin that she and Hamster can take care of themselves, only for a villain named Professor Exclamation to capture the two.

Chibi Tiny Tales is a series of shorts that depict characters from various Disney Channel properties in chibi-style animation.

The character of Hamster originated from a drawing he did on his sketchboard during development on the Disney+ film Phineas and Ferb the Movie: Candace Against the Universe (2020).

[62] The series was based on Povenmire's dynamic with his much younger sister, which he felt had never been portrayed on TV before;[55] director Amber T. Hollinger described the relationship between Kevin and Gretel as the series' main focus,[63] with Kevin's arc centering on his role as an older brother after Gretel receives her powers.

[64] The series is set in the same universe as Phineas and Ferb and Milo Murphy's Law, with characters from both shows making cameos throughout Hamster and Gretel.

[7] At San Diego Comic-Con 2022, Povenmire elaborated that while there were no concrete plans for a crossover, he remained open to the possibility after the first two seasons, as the staff were focusing on the show's own overarching narrative during that time.

He expressed interest in eventually bringing together characters from Phineas and Ferb, Milo Murphy's Law, and Hamster & Gretel.

[62] The series features action sequences that are more elaborate than those occasionally seen in Phineas and Ferb and Milo Murphy's Law.

Brandon Zachary of Comic Book Resources stated, "Hamster & Gretel delivers a new take on a lot of well-worn genres from Disney Animation.

It's quietly a solid parody of superhero narratives, with one of the minds behind Phineas and Ferb helping usher in a new generation of bizarre heroes and villains.

"[70] Tony Betti of LaughingPlace.com gave Hamster & Gretel a grade of 4 out of 5 stars, saying, "At only a few episodes in so far, the show has already started building a universe that is sure to become lush and full of details and recurring characters that we will likely see throughout.

"[71] Diondra Brown of Common Sense Media gave the series a grade of 3 out of 5 stars and praised the depiction of positive messages and role models, stating the characters promote self authenticity, friendship, and helpfulness, while noting the diverse representations across the racial and religious backgrounds of different characters.
