Knuckles’ obstacle course is a Sonic level made out of rocks and logs
Right as the show opens, we see Knuckles has made himself an obstacle course outside his new Earth home, following the events of Sonic the Hedgehog 2. This includes hazards and props that are homage to Sonic games, such as the spiky iron balls and crushers that could squish Knuckles into a Sonic-branded pancake. But there’s also a goal signpost at the end that, once Knuckles reaches it, shows a chalk drawing of his face similar to the ones that would show up at the end of levels in the 2D Sonic games.
