SpongeBob's journey through relativity is the perfect physics glow-up story! Starting with the naive "time is constant" (so cute, so wrong), then graduating to basic time dilation, before flexing with Lorentz transformations, and finally reaching enlightenment with 4D manifolds and mass-energy distribution. It's like watching someone evolve from "the Earth is flat" to "spacetime fabric bends near massive objects" in four panels. Einstein would be proud seeing a cartoon sponge explain how time isn't the rigid ticking clock we imagine, but a flexible dimension that warps based on your reference frame. The final panel is basically what happens when SpongeBob stops flipping patties and starts reading graduate-level physics textbooks!
