Hally is a kind pup and loves being with other pups and people, she's very mature for her age and tends not to play rough and tumble games, she prefers to just sit by and watch. When it comes to cooking Hally can be a very strict chef, she doesn't allow taste testing her kitchen and always makes sure that the dishes are done and the kitchen is tidy.
She's got a huge crush on Clemens. The two first met at the Lookout when Viktor came down from SnowPort with his siblings to visit Mindy. Clemens found himself wandering around the Lookout and eventually winding up in the kitchen, where Hally was cooking for the PAW Patrol crew. The two spoke and Hally told him about Adventure Bay and her time as a PAW Patrol member. Clemens tried to help her bake but it soon resulted in a big mess. Afterwards Hally took him on a tour of the Lookout and Bay and the two got close after that.
she doesn't like cars and other vehicles because of the loud noises.
Her voice actress is Elizabeth Dampier, the voice of young Tatiana from the princess and the frog.
