Do you have a little Scaredy-cat on your hands? It happens. How did you ease their fears? Did you make them face it head on? Mo Willems’ new book, Sam, the Most Scaredy-cat Kid in the Whole World, the follow-up to Leonardo, the Terrible Monster would be the perfect companion for your child. To make the experience even more fun, I’m sharing a DIY Monster Slime tutorial. Your child can share their slime with friends and family! The slime can be stored in a container and labeled for any occasion or celebration. Plus, I created free monster tags/labels that you can print right from your printer! 

DIY Monster Slime Tutorial

Monster slime supplies


  • 5 fl oz clear glue
  • 1 tsp Baking Soda
  • 1.5 tsp of Saline Solution
  • Food coloring
  • Glitter
  • Assorted wiggly eyes
  • Measuring spoons, mixing tools, and bowls


  1. Pour the clear glue into a mixing bowl. Add the food coloring (I added about 4 drops of green for the Green Monster Slime). Mix well.
  2. Add the glitter and mix well. Next, add the wiggly eyes.
  3. Slowly add the Baking Soda. Tip: I added slowly while mixing so the mixture doesn’t get white clumps.
  4. Carefully add the Saline solution. 1/2 tsp at a time while you mix. The mixture will start to separate from the edges and gets really sticky.
  5. With your hands grab the sticky slime mix and move it around in your hands. After a few minutes, it will be perfect – no longer sticky.

Home made Slime

Once you get the hang of it, making slime is SO easy! I did it with my kids and my son was able to do a batch on his own. I made a few adjustments to my first batch as it was hard (which means I used too much baking soda). I checked my measurements and the second batch was perfect, which is the tutorial above. If you notice your slime is too hard – use less baking soda, if it is too sticky – use add more Saline solution.

My daughter can be a little shy especially when it comes to meeting new people. If your child has a hard time talking to others, the slime can be a great gift to give. It is fun and everyone loves slime! I created these printable Monster slime labels saying, “Thank you for being a Monster-ously good friend”. I hope this project and Mo Willems book helps your little one.

About Sam, the Most Scaredy-cat Kid in the Whole World


Sam is afraid of anything and everything—except for his friend Leonardo, the terrible monster.
Kerry is afraid of everything and anything—except for her friend Frankenthaler, the other monster.
One day, the two scaredy-cat kids make a particularly scary discovery: each other!
AAH! EEK! Something has to be done. Something BIG. But what?

Monster slime DIY

I read the book to my daughter because she is sometimes scared of approaching other kids her age. I am glad she is cautious but if it is a little girl or boy we see over and over – there is no reason for her to be scared. We attend my son’s baseball games 2x a week and there is always a little girl there but my daughter was too scared to talk to her. We read Sam, the Most Scaredy-cat Kid in the Whole World a few times and you know what? She slowly started playing with her. My daughter brought her big bounce ball and asked the little girl if she wanted to play. All it took was a little confidence. Now, they are the best of friends and play together every single time. She plans to share some DIY Monster Slime with her.

Those moments make me so proud.
