Ever done Pokémon pumpkin carving before?
Here's a simple idea to start - you can never have enough Pokéballs! Don't forget to ask a grown-up for help before trying your own carvings.
Start off your pumpkin-dex with something simple!
You can also peel away the skin to only let some light through, for more complicated pieces like Koffing's skull and crossbones.
If you get good at it, you can always choose a spookier Pokémon to carve...
