Marmite please

Its cheese and onion crisp time
I need my salt reserves
For S.A.D is coming
and protein I deserve

I crave for baked potato's

For extra foody starch
twill help with hibernation
From now until next March

Take care when you approach me
A bear is what I am
I'm looking for some comfort
between two joints of ham

The thought of sweets disgust me
Chocolate I do despise
Unless it wrapped in Marmite
to help with its disguise
