Xenon gets a haircut

He runs around near the office, a happy little chap into every sort of mischief. Always in the front row when the students are having their lunch and quick off the mark too. He's a sweet little fellow, very handsome but rather in need of a hair cut and a bit of a wash. Look at him now, all brushed and smart.

Ooh. Am I going to get a treat?

Later! What do you mean 'later'?

Can I go now?

Butter wouldn't melt ....

See, I'm being really good!

Can I have my treat now?
