Sadly, Steph's realization and shout did indeed come a little too late, as Amelia was already in the treeline and making her way in deeper, caught up in her little game with the Pumpkaboos.
Amelia found herself woerin for a while and was happy when she finally picked up on a ghostly presence after a bit of walking. She would follow it and eventually reach where it was it's strongest and closest. She looked around, trying to find it before eventually hearing the Pumpkaboo crying out. It seemed to come from above and indeed it was, as a glance up did indeed reveal the Pumpkaboo... who was stuck in a web... surrounded by Spinarak. She noted a skull on the web as well but it was soon revealed to be a different kind of Spinarak. Amelia could sense this Spinarak, meaning it was a Ghost-Type. If she had to take an educated guess, it was a Bug/Ghost type. She pulled out her two last empty pokeballs. She had one shot at the Pumpkaboo and one shot at the Spinarak. Given she was about to steal it's meal, she was expecting a battle. But if she didn't do this, Pumpkaboo might get hurt or worse.
"Pumpkaboo! Whatever you do, don't resist! Just stay in and you'll be safe!" She shouted at the little pumpkin before giving it a few seconds to or at least register what she said. From there, she would throw one of her empty pokeballs at it, hoping that it would stay inside and hoping the Spinarak wouldn't be too upset.
