Made private... Let's try this.
I'm assuming this is the same one? It's right in the beginning, but specifically at 1:25 on.
And as a bonus? An episode ABOUT Smoochum.
Smoochum gives out kisses a few times throughout the episode, but most of them are right after the opening, around 1:55. But near the end, at around 18:22, she actually uses Sweet Kiss. At 20:36, it's seen blowing Sweet Kisses all around.
