Puppet Walking postion Error

Question

I need help with my puppet. I want my puppet to walk forward and then stop then do a bit of dialog to the camera. When he is not walking he automatically t-poses, I don't want that to happen. But i have tried to fix this by dragging my character's arms into the position and then when he tries to walk again, his walking cycle is not right. How would i go about making it, all i want is for his hands to be by his sides when he is not talking then the normal walk after. If anyone can help I would be really appreciative. I have attached a video where it shows that is happening. I have also attached the puppet and the illustrator files. Thanks In Advance
