Our Elf called Bob by Niamh

Our class have an elf called Bob. Bob is VERY  naughty. He ate some of our chocolate.  He is also quite a tidy elf but just a few days ago he stuck himself to the wall and on the 5th of December he graffited  on table. He wrote: HAVE FUN AT THE PANTO. On the 12th he made paper snowflakes.  What else he will get up to?
