• command_list_id – The ID of the command list the frog will use.
• initial_as – The frog’s initial animatory state.
• location – The frog’s initial location.

check_heads()

Check whether this frog has hit anybody’s head, and take appropriate action (such as handing the safe key to Eric) if so.

A mouse.

Parameters:

• mouse_id – The ID of the mouse.
• command_list_id – The ID of the command list the mouse will use.
