As you were walking in the Math Void, you see 3 symbols, those symbols are: Zeta, (ζ) Phi, (φ) and Delta (δ). Zeta was jumping for walking, Phi was just teleporting for walking, and Delta is flying with its tail moving, they don't seem to notice you until you get their attention

Zeta: Oh wow! Another living being!!, what's your name??

Phi: Oh yeah what's your name dude?

Delta: Flying gleefully because it doesn't have a mouth
