We need at least three encounters to endlessly cycle and create a never-ending world; two can be on the screen at any one time and a third positioned ahead of the player. We can track Pierre's progress and reposition the encounter nodes ahead of him.

EncounterCoins.sks. You can completely fill these encounters with bees, ghosts, blades, coins, and bats – have fun!
For inspiration, here is my bee encounter:
