Answer:
elastic force?
well I hope im giving you the correct definition...
something that is elastic can be stretched or compressed.
For example a bungee cord(search up). It resists the change of shape even when stretched and compressed. And because of that it applies a counter force in the opposite direction in which you would call a elastic force.
Because the tongue is pinkish and sometimes it is an animal because it possesses the bad or wildness of an animal.
