Halloween highlights at UCalgary

We stopped by the Halloween costume contest in the Engineering complex—with a little trick and lots of treats!

UCalgary mascot Rex dressed as a Labubu for Halloween
The star of the day? In our (biased) opinion, it was Rex, who stole the show dressed as Labubu.

This Halloween, the campus buzzed with energy as everyone got into the spirit, proving that midterms can’t scare off our fun. Instead of heading out to collect candy, Rex flipped the tradition with a reverse Trick-or-Treat, handing out candy across campus dressed as an extra-rare Labubu.

Check out our favourite costumes from the day below.
