Now this is how you kick off a summer of fun. Neil Patrick Harris recently brought his and husband David Burtka's 5-year-old twins on a trip to the Vancouver Aquarium in Canada, and it looks like they had a smashing good time.

Harris took to Instagram to share a video from their excursion, and it features a too-cute Harper happily watching a pair of otters as they play in the water. And although her equally adorable brother Gideon isn't in the clip, we can bet he also enjoyed the sweet swimming animals. But it wasn't all just about having fun—the visit was also educational. "The Vancouver Aquarium is stellar! Loved it! The kids learned all kinds of new things..!" the actor captioned the video post.

The duo recently graduated from preschool, and the proud dads marked the occasion on social media. To celebrate, the two cuties played on the playground while wearing darling warm weather-ready outfits.

We can't wait to see what Harper and Gideon get up to next.
