Shot starts with showing Thor picking up the pieces of the broken Mjollnir, looking at the shattered pieces in fond memory before he leaves through the Bifrost.
Camera pans down to show a fragment lost in the grass and dirt still laying there.
There is a croaking of a frog as one jumps into frame as the camera zooms out.
The frog approaches the fragment, possibly going after an insect in the grass all while the camera continues to zoom out.
Finally as the field/cliff is shown in a wide shot there is a bolt of lightning that strikes down where the frog and fragment was.
As the thunder rumbles and fades there is a powerful and loud croaking that echoes as the screen goes black.
If they won’t give us Beta Ray Bill they should at least give us Throg
