I think the three Monster Cereal characters: Count Chocula, Franken Berry, and Boo Berry would make cool patterns for this year. You can only get the cereal around October anymore so it is fitting for the season now a days.
Count Chocula
Franken Berry
Note to self, I should try to do that with the rest of the Cereals.
Boo Berry
If you also feel like doing the discontinued Monster Cereal characaters: Fruit Brute and Yummy Mummy on your off time.

Yummy Mummy
Yeah I know 3 - 5 of the same class is a bit much, but I would be very greatful.
