Kidrobot’s Adventure Time Mini Series is more than a Finn-and-Jake character sampler. The 3-inch blind-box assortment reaches across Ooo, then mirrors part of the cast with the gender-swapped Fionna and Cake universe. A timestamped unboxing shows the series was already in collectors’ hands by June 2015, placing it squarely in the show’s original television run rather than among Kidrobot’s newer large-format Adventure Time art figures.
An 18-design trip through Ooo and its parallel cast
The box announces “grab all 18!” across two character panels. The core heroes and rulers are here: Finn, Jake, Princess Bubblegum, Marceline, BMO, Gunter, Ice King, Flame Princess, Lumpy Space Princess, Magic Man and the Lich. Kidrobot also made room for a second Finn equipped with the grass sword.
The assortment becomes more distinctive when its parallel-world characters are counted. Fionna and Cake appear beside Prince Gumball, Marshall Lee and Ice Queen. That gives the series five direct counterparts rather than treating Fionna as a one-off variant. The final slot is represented on the package by a black mystery silhouette, so the exterior deliberately withholds that design’s identity.
What the printed odds actually say
The photographed package supplies unusually useful ratios. Finn is marked 2/20, while Jake is 3/20. Gunter and BMO are also 2/20. The grass-sword Finn, Princess Bubblegum and Ice King each read 1/20.
The 3/40 group consists of Flame Princess, Lumpy Space Princess and Marceline. Fionna, Cake, Prince Gumball and Marshall Lee are each printed at 1/40. Those ratios make the counterpart characters meaningfully less common than most of the central cast, without requiring collectors to guess from aftermarket prices.
The package’s standout disclosed rarity is the Lich at 1/80. That is strong evidence for describing the Lich as a collector chaser or chase-level pull: statistically, it is short-packed far beyond a normal 1/20 design. It is not evidence that Kidrobot officially branded it as a capital-C “Chase,” so collectors should keep those terms separate. Magic Man and the silhouetted mystery design have question-mark odds on the photographed panel. Because their ratios are intentionally hidden, the box does not support claiming either one is rarer than the 1/80 Lich.
Reading the box before adding it to a collection
This is a true mystery purchase: Finn and Jake decorate the front, but that artwork does not identify the figure inside. The photographed example remains in its closed cardboard box, yet the available views do not show intact factory seals or every flap. A closed box should therefore not automatically be described as factory sealed.
Condition-focused collectors should also inspect the exact unit rather than relying only on the colorful front art. The photographed box shows a crease or dent near the upper-right front corner and light handling wear along some edges. That may be perfectly acceptable for an opener, but it matters to anyone building a package-first display. Ask whether the character card and any accessory are present if buying an opened example; none can be confirmed from exterior photos alone.
Who this series suits
The strongest reason to collect this set is its internal pairing. Finn, Jake and Princess Bubblegum can be displayed directly against Fionna, Cake and Prince Gumball, while Marceline and Marshall Lee create another obvious duo. The grass-sword Finn adds an episode-era costume detail instead of merely recoloring the standard hero. For character collectors, that makes the checklist feel curated around relationships and alternate-world echoes rather than a random stack of eighteen faces.
Blind-box buyers should weigh those display possibilities against the long odds. A single box is a fun character pull; it is not a practical route to a complete set or a guaranteed Lich. The BlindBoxes product page shows a price of $11.99, but stock can change, so confirm availability before ordering.
