I have predictions of what could happen in both the specials: First and foremost, both would teach the concept of algebra. The simplest bits of it, to be exact. I know both shows are for preschool kids, but that could be a great possibility. Making Friends could teach the stuff that is “a + 1”, “d - 4”, ect. which is a good possibility. However, I thought of a more interesting idea for the other crossover special (The one with Octonaughty in it): It could teach the stuff that is “8x” which is 8 multiplied by x. Now this might seem dym to some, but there could be, there COULD BE, a possibility of 48, 56 and 72 officially appearing figured out, as they’re multiples of 8, and the “8x” could mean any number multiplied by 8 (But not to the extreme like 8 times 29). They might not appear, but this IS a possibility. This project/image shows how this could work.
