Corel Draw 7.0 how can i finish the company logo?

Hi,

i want to make a logo with corel draw 7.0(older version not x7!) but i have problems with making a cutout of the squirrel so that the green back colour is the same. 

I would be very pleased to get some help how to change the squirrel bitmap with cut or make the same back colour.

Thanks in advance,

Florian
