    Fall Leaves + mystery slime 10/10

    I got the fall leaves slime and a mystery slime, and I have to say I'm SO happy with the products. The mystery slime was a vibrant neon green tag with a clear base called Biohazard. I loved the texture, the color, the smell, the unique and creative idea. 10/10, such a fun surprise. The crunchy leaves slime was GORGEOUS, speckled with shifting glitters that made me gasp upon opening it. The package shipped SUPER quick, super safe, amd came with lots of cute little freebies!!!! If you haven't bought from Mushbunny, you're missing out!!! Their small team is sweet, Creative, and we'll organized!!!!


    I received mothman with an adorable little pin. I appreciate when newly released slimes are used for the mystery.


    I absolutely love this as an option. This company is amazing and I haven’t had a bad slime from them. I find myself getting so excited over the “mystery” slime when I open my box. Like, what slime is it going to be?!?


    I was hoping I’d get a crunchy slime and I got the meteorite slime <3 I was so excited I love it! Came super fast too can’t wait to buy more
