His tail is getting impatient. It wants to eat some of the candy Scifen has gathered but he has to make sure they're safe to eat!
Remember Trick or Treaters, ALWAYS inspect your candy before you eat it!
If it has a tear or looks tampered with, tell a parent or guardian!
And do not accept home-made treats (or if you do to be polite, just discard it the next chance you get) unless they're made by someone you know and trust!
I hope you all have a fun, safe Halloween!
