Original Description:
 
This is something I wanted to draw for months! Here, we see Gallus and Grandpa Gruff daring each other to a friendly arm wrestle. As you can see, Gallus struggles to a bit keep up with his grandfather’s strength. Actually, Grandpa Gruff’s arm has hardly even MOVED! XD You might remember that Grandpa Gruff got into an arm-wrestle with one of his friends a little while ago, and I thought it was only fitting for him to have another match, this time with his favourite (to affectionately annoy and tease, at least :lol: ) grandson, Gallus. Who do you think will win? Hope you like it! ^^
