Serina

Hey fellow collectors! If you are looking to add some serious magic and vibrant color to your display, Serina from the Mermaid Roller Coaster Ride is an absolute showstopper. Minidoll collectors know how rare it is to get such intricate fantasy detailing, and Serina delivers in a big way with her stunning opal trans-purple curly hair and gorgeous sienna brown skin tone. That sea shell necklace print paired with the gold trim on her top makes her look like true royalty of the amusement park rides.

When you are inspecting this figure for your collection, pay close attention to the print crispness on the warm pink hips and fishtail. The metal pink and gold decorations are a standout feature that will make this piece pop in any coastal or theme park MOC. Because minidolls feature unique molded hair pieces and specialized lower bodies like this mermaid tail, keeping all four original components together in pristine condition will be crucial for long-term display value.

Serina currently holds a high exclusivity factor because she is only found in a single large set, the 2026 Mermaid Roller Coaster Ride. Figures tied exclusively to large, higher-priced amusement park sets often experience tighter supply on the secondary market compared to figures spread across multiple budget-friendly impulse buys.

As a brand-new addition to the lineup, aftermarket availability is still stabilizing, and market data suggests that fans breaking down sealed sets will be the primary source for acquiring her. If the set enjoys a standard retail shelf life, she will be moderately available, but once retirement hits, expect the hunt for a complete, undamaged Serina to get significantly tougher.

Looking at the investment potential, amusement park and fantasy-themed minidolls tend to build a dedicated following among builders who love vibrant, colorful layouts. Since Serina is locked behind a $109.99 set, the barrier to entry for acquiring her individually from scalpers or part-out shops might keep demand steady among completionists who do not want to buy the whole coaster.

However, investors should keep in mind that theme park sub-themes can sometimes experience fluctuating demand compared to heavy-hitting licensed properties like Star Wars or Marvel. If the Mermaid Roller Coaster theme resonates strongly with builders, Serina could see solid upward momentum post-retirement, but if the set languishes on clearance, her aftermarket growth could face an uphill battle. Keep a close eye on market data trends as the set ages toward retirement.
