At the beginning of the story with Mabel, you can "remove" (i.e. adjust) the ladder in front of the school entrance at night when Mabel is about to enter the school in order to steal the exam questions (i.e. Thursday's evening 19+ PM).What fence does Mabel get stuck in? Been playing the game for a while and already got 2 Fs. But still havent seen this ever.
Mabel will be then stuck in the school fence.
