I once found this on the internet:
But I haven't tried it myself yet...

The Basic Vehicles are the perfect size for the Paw Patrol tower.
In addition, all figures from the Action Pack Pup series fit this playset
The Deluxe vehicles are not compatible here!

My daughter has this station and it always fits the set (car and figure). All the cars sold by Galaxus actually fit. Except for one set, which has several cars that would be too small

I couldn't find what I was looking for either.it would definitely be the ..ones that are like the blue one

There's only one car and one figurine (Chase)
