Tinkles (originally known as the Puppy, and also known by his human disguise Bob) is the main protagonist of Puppy! and Monster Pets and a major character in Hotel Transylvania 3: Summer Vacation. He is pet of Dennis.
He is voiced by Joe Whyte from Puppy!, third film and Derek Drymon from Monster Pets and fourth film.
He is a giant black puppy and wears red collar.
Tinkles jumps a lot when he's excited. He's easily obedient when bribed by meat.
Tinkles was obtained by Count Dracula when Mavis and Johnny think that Dennis having a pet is too much of a responsibility. He does cause some trouble for Count Dracula.
Hotel Transylvania 3: Summer Vacation
Dennis sneaks Tinkles on the vacation that Mavis plans for Dracula.
After Dracula and Mavis are caught in the Kraken's tentacles, and begins to violently suffocate Dracula, Ericka couldn't bear to watch Drac get hurt, so Ericka jumps off the DJ booth, (Much to Abraham's shock, and surprise) and jumps onto Tinkles, and using her martial art skills, kicks the Kraken in the eye, making the large sea creature growl in pain, as Ericka watched a seemingly lifeless Drac, fall from the sky. Ericka jumps off the massive Tinkles.
A month later, back at Hotel Transylvania, Drac asked Ericka to marry him.
After stammering nervously, Dracula, Mavis, Johnny, Dennis, Tinkles and all the other monsters, were waiting eagerly for Ericka's answer, then Ericka blurts out happily: "YES!". While the monsters cheered, as Drac and Ericka share a romantic hug, while Tinkles chase after them.
