Pryce used his Seel to look after the Gym. He also had them transport statues he crafted and sell them. After Suicune was defeated in his Gym, Whitney went to catch it, but left a hole in its body. Pryce admitted he actually had his Seel and other Pokémon freeze the air and craft Suicune, making it look as if it were moving. He also admitted he did this to train to catch Suicune one day.
None of Seel's moves are known.
