In the depths of my heart can be found a place barely accessible to anything, cold and barren. But like a Russian Sleeper agent or Denzel Washington in The Manchurian Candidate, this heart can become triggered into action instantly by the incantation of a single phrase.

There exists a Stardew Valley mod that lets you play fetch with your pet, and your pet will follow you around everywhere.
