The GUI GUI Mega Slime Haul is a $30 box of five scented slimes plus tools, figurines and decorations, built around a step-by-step slime "beauty routine." For a kid who watches slime videos on repeat, it's a great gift with a big unboxing. If they only want slime to squish, you're paying for a lot of extras they won't care about.
What It Actually Is
GUI GUI is Moose Toys' slime line, and its twist is treating slime like a skincare routine: you prep it with "beauty tools," mix in a booster, decorate it and finish it with a cute figurine. It's playing right into what kids watch on slime and unboxing channels.
The Mega Slime Haul is the big set from Series 2. Inside you get five slimes in different textures, from fluffy cloud slime to crunchy slime, along with a vessel, two tools, four figurines, nine deco packs and a charms clip. The mini crunch slime, Lil Flutter, is exclusive to this set and has a cherry blossom scent.
The tools are the part that makes it feel premium. The Gua Sha tool is for smearing and sculpting, and the 3-in-1 tool scoops, drizzles and rolls. It's a lot more to do than poking a tub of slime.
The $30 Math
Moose Toys lists the Mega Slime Haul at $32.99. Here's how it compares to the smaller GUI GUI set:
| Set | Price | Slimes | Best for |
|---|---|---|---|
| Mega Slime HaulSeries 2 | $29.99 | 5 | A big birthday or holiday gift |
| Fruity Glow Deluxe Twin PackSeries 2 | $19.99 | 2 | Trying GUI GUI for less |
You get more than twice the slime and a lot more accessories for $10 more. If your kid already loves slime, the Mega Slime Haul is the better value. If you're not sure they'll care about the beauty-routine part, start with the twin pack.
The Good and the Not-So-Good
Where It Delivers
- Five textures in one box, so there's something for every kind of slime fan.
- The tools and deco make it more of an activity than a tub of slime.
- It's a big, satisfying unboxing for a gift.
- The exclusive mini slime is a nice collector touch.
Where It Falls Short
- Slime is messy, and glitter and charms make it messier.
- Slime doesn't last forever. Leave the lids off and it dries out.
- A lot of what you're paying for is packaging and accessories.
- Strong scents aren't for everyone.
Our Read
GUI GUI gets what slime kids want right now. It's not just slime, it's the routine, the textures and the decorating that they see online, all in one box.
For a kid who's already slime-obsessed, it's an easy win. For a kid who's lukewarm, a $20 twin pack is plenty.
What To Buy Instead
Who It's For
Buy It If
- Your kid loves slime videos and mixing in add-ins.
- You want a gift with a big unboxing moment.
- They like collecting little figurines and charms.
- You're fine with a slime station at the kitchen table.
Skip It If
- You're not ready for the mess.
- They only want slime to squish. A basic pack is cheaper.
- They're under 6.
- Anyone in the house is sensitive to strong scents.
What You Should Actually Pay
About $30 is a fair price, a few dollars under the $32.99 list. If it dips into the low $20s around Black Friday, that's a great deal for a holiday gift.
