"Starstruck" is the first segment of the eighteenth episode of Star vs. the Forces of Evil. It premiered on August 8, 2016 alongside "Camping Trip", and is the first segment of the fifth episode in the second season.
While foraging for donuts that are being tossed at the end of the day, Star encounters Mina Loveberry, a magical girl from Mewni who is Star's idol. Mina has been living as a homeless person on Earth. Star follows Mina and tries to train in her ways, which annoys Marco. At a park, when Mina announces she plans to take over the world, the people decide to hold a vote on whether Mina should rule, and Star is left to break the tie.
- Mina Loveberry's appearance loosely resembles Sailor Moon, who was also one of Daron Nefcy's inspirations for Star Butterfly.
