To kick this one off:

Beverly the Beaver

Why/ I can just hear your Japanese students saying "Beevorlly the Bayvoor" can't you?

Hamish The Beaver (of course you could't afford the 97 kilt closet)

Jamie The Beaver (Ditto the natty togs)

Mac Burdo the Beaver

Best for last:

Pleater the Beaver (of course she would need a tartan jacket and matching bonnet)

Cheers
