It will remain in the cold environment.

It will become hungry.

It will move to a warmer spot.

Explanation:

An ectotherm will move to a warmer spot if they found themselves in cold temperatures because they are not tolerating good cold temperatures. If they do not have any other options they will run toward the stimulus which means that they will try to bury themselves and hide from cold temperatures and in that way they will have to remain in the cold environment.
