After being shuffled from Potions to Magical Creatures, I have tried to give the students the benefit of my extensive experience with various beasts and varmints unknown to the general muggle population. Unfortunately, it appears that the children are not interested in learning about such things, and I once again am summoned before Dean Santa to explain myself.
I attempt to educate Santa on the nature of the ninja hedgehogs, but my words are disregarded.
It certainly is difficult trying to convince the hidebound bureaucracy of facts that do not fit their preconceived notions of how the world works and who can and cannot be a ninja.
Fortunately, Dogwarts is still having difficulty attracting and retaining qualified staff, and rather than being let go I am transferred to yet another new department. As this is not my area of expertise, I decide to bring in outside assistance this time.
Surely this time the children will appreciate my efforts! After all, I am Dennis the Vizsla, and I never give up.
