WWE figures are usually made of a hard plastic, which can make them difficult to loosen if they become stuck. There are a few things you can try to loosen your figure.
One method is to boil some water and pour it over the figure. Be careful not to get the water too hot, as this could damage the figure. Another method is to put the figure in the freezer for a few minutes. This will cause the plastic to contract and hopefully loosen the figure.
If neither of these methods work, you may need to use a knife or other sharp object to carefully pry the figure loose. Be very careful not to damage the figure while doing this.
