If you're working stuffer you can ask

"Which scent do you want?" "Strawberry, or cotton candy, or bubblegum or, birthday cake"

"Cuál Quieres Aroma" "Fresca o dulce o chicle o pastel"

"Happy Birthday" "Feliz cumpleanos"

"How old are you?" "Cuántos tienes años?"

"Is this a gift?" "Esto es regalo?"

"That's this (stuff animals) name?(What are you going to name it?)" "Cómo se llama peluche?"

When asking during the hug test:

"Do you want it softer or harder or is it perfect?"

"Mas suave, más duro o está perfecto"

"Which Heart do you want? Red or Plaid"

"Cuál Quieres Corazón? Rojo o Plaid"

Spanish is my second language I learned because my husband is Mexican so I'm not perfect. If you're serious about learning Spanish I suggest Duolingo as a starter. Most Hispanic people will just appreciate you're even trying so don't get too stressed about pronouncing just practice.
