It's business as usual after the sun-kissed adventure in Hotel Transylvania 3: Summer Vacation (2018), and Count Dracula has a lot on his plate already. But, as if that weren't enough, Tinkles, little Dennis' cuddly but indomitable pet from Puppy! (2017), is looking for someone to play fetch with. Now, to channel the endless supply of energy of the lively canine giant, the always-busy head of Hotel Transylvania (2012) attempts to find a suitable playmate for his grandson's furry companion; however, that's easier than done. Is there a friend out there for Dennis' monster pet?
