LEGO has officially pulled back the curtain on 72537 Derpy Tiger and Sussie Bird, the first set based on K-Pop Demon Hunters. The reveal gives the upcoming theme a proper starting point, and it is a memorable one. Instead of leading with a vehicle or a location, LEGO is opening with a character-driven build that leans into the film's playful energy and the oddball charm of its breakout animal duo.
The clearest product details come from The Brick Fan's announcement, which confirms that 72537 launches on August 1, carries 825 pieces, and will retail for $69.99 in the US. The set centers on Derpy Tiger and Sussie Bird, with display-friendly posing, alternate facial expressions for the tiger, and small accessories including love notes and a flowerpot. There is also a storage compartment tucked into Derpy's head, a detail that gives the model a little extra play value beyond its shelf appeal.
On its own, that would already be enough to put the set on the radar of collectors who follow new licensed themes. What makes this reveal more interesting is the added context from Brick Fanatics, which spoke with members of the design team after the announcement. According to that report, the internal push to get the character's look right came down to one specific feature: the eyes. That makes sense the second you look at the model. Derpy Tiger is not a realistic animal build, and it is not supposed to be. The oversized expression and slightly absurd face are doing most of the work, so if the eyes missed the mark, the whole model would lose its identity.
Brick Fanatics also notes that the turnaround for the set appears unusually tight. LEGO only announced the K-Pop Demon Hunters partnership in February, which suggests this model moved from concept to release-ready form on a compressed timeline compared with many standard in-house sets. That does not automatically make the set better, but it does explain why the design story matters here. A short runway usually forces teams to focus on the features that absolutely have to land, and in this case the character read seems to have won out over unnecessary complexity.
Jay's Brick Blog adds one more useful layer of context by framing 72537 as the first step in something larger. Its report says more products tied to K-Pop Demon Hunters are expected in 2027, which makes this release feel less like a one-off experiment and more like a test case for how well the property translates into brick form. If that roadmap holds, 72537 has a job beyond simply selling itself. It has to establish the visual language for the rest of the range and prove that the movie's stylized world can survive the jump into LEGO form.
That is probably why the set feels so character-first. The poseable build, the expression swap, the comedy props, and the strong silhouette all point to the same goal: make this instantly recognizable to fans of the movie and visually legible to people who have never seen it. Licensed LEGO themes do this in different ways. Some rely on icons and logos. Others lean on minifigures. Here, LEGO is betting that a single sculptural build with enough personality can carry the introduction.
It is also a smart choice for the current market. Display sets with a playful edge have been performing well across multiple themes, especially when they live in that space between toy and collectible. 72537 seems designed for exactly that lane. Younger builders can get a colorful character model with moving parts, while older fans get something unusual enough to stand out from the usual lineup of ships, helmets, and architecture builds.
There is still plenty we do not know about the full K-Pop Demon Hunters rollout, but the first impression is strong. LEGO could have played this safe. Instead, it chose a set that is specific, weird, and immediately tied to the identity of the source material. If the rest of the theme follows that same instinct, K-Pop Demon Hunters could end up being one of the more distinctive licensed launches on the calendar.
For now, 72537 Derpy Tiger and Sussie Bird looks like a solid debut: 825 pieces, an August 1 release date, a $69.99 price point, and enough personality to make the set feel like more than a simple tie-in. The reveal is not just about another new LEGO product hitting shelves. It is the first real sign of how seriously LEGO plans to treat this license, and on that front, the company has made an opening move that is hard to ignore.
