I have been trying to identify the geometrical font used on this Suga Rush advertisement image. I circled it so that it can be distinguished from the actual Suga Rush font itself. I need it to use in creating a coloring/workbook to distribute to students who may still be quarantined when school starts. It’s a fun, happy, yet clean font, perfect for the kids!

Can anyone help me?

Given that appears to be a Creative Fabrica font, have you looked through their catalog? E.g. their sans-serif fonts?
