What's inside each Mystery Squad pack
Collecting the Mystery Squad 300 Series
The Mystery Squad 300 collection represents our largest mystery series to date, featuring characters from every Squishmallows squad we’ve ever released. You’ll find woodland creatures, ocean friends, fantasy dragons, food-themed buddies, and seasonal characters all randomly assorted across the 300-character roster.
Each character is assigned a rarity tier clearly marked on their collectible card. Common characters appear frequently and help you build foundational squads. Rare characters feature special design elements like glitter accents or unique color combinations. Ultra-rare variants include holographic tags, exclusive patterns, or character debuts making their first appearance in mystery format.
Mystery Pack Contents & Unboxing
Every Mystery Squad 300 blind bag contains one 5-inch Squishmallow sealed in protective plastic, plus one collectible character card. The outer foil bag conceals the character identity completely — no feeling the bag reveals which plush is inside.
Your character card provides the full backstory: name, personality traits, favorite activities, birthday, and squad affiliation. The back of each card displays the complete squad checklist, helping you track your collection progress. Rare and ultra-rare cards feature special foil stamping and holographic elements.
Care Instructions for Mystery Squad Squishmallows
All Mystery Squad 300 characters feature our signature ultra-soft polyester exterior and marshmallow-like polyester fill. To keep your collection looking fresh, machine wash on gentle cycle in cold water with mild detergent.
Place Squishmallows in a protective mesh laundry bag before washing to prevent pilling and maintain their soft texture. Air dry completely — never put Squishmallows in the dryer, as heat can damage the polyester fibers and cause shrinking.

Mystery Squad 300 Collection Questions
The Mystery Squad 300 series features over 300 unique characters spanning all our popular Squishmallows squads. The collection includes woodland animals, ocean creatures, fantasy characters, food friends, and seasonal exclusives.
We rotate character assortments regularly, so the available characters may shift slightly with each production wave. The 300 count represents the total character pool we draw from when packing mystery bags.
Common tier characters appear in approximately 60% of mystery packs. Rare tier characters (featuring special design elements) appear in about 30% of packs. Ultra-rare characters with holographic tags or exclusive variants appear in roughly 10% of packs.
The Mega Pack doesn't change individual character odds, but gives you five chances to pull rare variants. All rarity distributions are randomized, so results vary by purchase.
Yes, duplicates are possible across multiple purchases — that's part of the collecting experience. Each mystery bag is randomly assorted from the full character pool.
However, our Mega Pack (5-pack bundle) guarantees no duplicates within that single pack. This makes the Mega Pack the best option for collectors who want variety. Many collectors trade duplicate characters with friends to complete their collections.
Because Mystery Squad 300 packs are blind bags with randomized contents, we cannot accept returns or exchanges based on which character you receive. All mystery packs are final sale once opened.
We recommend using our official Trade Zone platform to exchange duplicate characters with other collectors. This community-driven approach helps everyone complete their favorite squads.
Yes, every Mystery Squad character includes our official embroidered Squishmallows tag sewn into the bottom seam. The mystery packs also include collectible character cards with bio information, squad details, and rarity indicators.
Ultra-rare variants may feature special holographic tags or exclusive card designs. Keep both the plush tags and character cards to maintain collectible value.
All Squishmallows in the Mystery Squad 300 series are 5 inches tall. This compact size is perfect for collecting, displaying in our official display case, and trading with other collectors.
The 5-inch size uses the same ultra-soft materials and quality construction as our larger Squishmallows, just in a more collectible-friendly format.
Genuine Mystery Squad 300 Squishmallows feature our embroidered official tag on the bottom seam, high-quality ultra-soft polyester materials, and come with a professionally printed character card with proper foil stamping.
Check our collector's guide for authentication details including tag placement, stitching quality, and card design elements. Counterfeit products typically have printed (not embroidered) tags and lower-quality materials.
