Ep 17. Equestranauts

In the episode "Equestranauts" of Bob's Burgers season 4, Louise becomes obsessed with the fictional animated television series "The Equestranauts," which focuses on a group of girls who protect a fantasy kingdom with the help of their magical ponies. Louise convinces her family and friends to attend the Equestranauts Convention, a fan convention dedicated to the show, but encounters a problem when they can only afford four tickets for the five of them.

Desperate to attend the convention, Louise decides to dress up as one of the characters from the show and pretend to be a guest star in order to sneak in. The group splits up at the convention, with Tina and Gene exploring the merchandise and Bob and Linda venturing off to try the convention's signature dish - a burger with donut buns. Meanwhile, Louise struggles to maintain her disguise and avoid being discovered as a fraud.

As the day progresses, the Belchers encounter a number of colorful characters at the convention, including a competitive father and son cosplay duo, a man who believes himself to be the real-life owner of the magical ponies from the show, and a group of rowdy college students dressed as the Equestranauts' arch-nemeses.

Despite her initial success in fooling the other fans, Louise's charade is eventually discovered by the convention's host, a former Equestranauts voice actress who is bitter about being replaced by a younger actress. The host threatens to have Louise kicked out of the convention, but Louise is saved when the real voice actress shows up and vouches for her.

By the end of the episode, the Belchers reconnect and share their various convention experiences. Tina and Gene have bonded with other fans over their love of the show, Bob and Linda have enjoyed a unique culinary experience, and Louise has learned the importance of honesty and authenticity. The episode ends with Louise contemplating her next cosplay idea and the family sharing a group hug.

Overall, "Equestranauts" is a fun and lighthearted episode of Bob's Burgers that celebrates fandom and the power of imagination. The episode's themes of honesty and authenticity also serve as important reminders for viewers of all ages.
