Timmy is a humpback whale. He is now free in the sea. He swam in the Baltic Sea for a long time. The water was too shallow there. The whale was stuck on the land several times. A private group saved the whale. They moved him to the North Sea by ship. They released him there on Saturday.
Experts from a museum are worried. They think Timmy is dead. The whale was thin. He was weak. He had no power to swim. It is hard to swim in deep water. The museum says the rescue was dangerous.
We have no new data about the whale. A GPS sender was on the whale. A GPS sender shows the place on a map. But the sender sends no signals. The group says the sender is broken. Experts want all data now. They want to know what happened to Timmy.
