There is a passage in Dream Journey in which Hector takes MiG to borrow a guitar. Brother pigskin asked him to return his thigh bone as soon as he met him. I didn't quite understand this paragraph when I first started watching this movie. Why did pigskin ask Ekto for thigh bone? Now think about it carefully and find that their friendship is so sincere. You know, bones are an indispensable part of them. Brother pigskin can lend his thigh bone to Hector, which shows that he has great trust in Hector. In fact, netizens have a lot of speculation about why pigskin lent his thigh bone to Ekto.
Some netizens speculated that it was because of Ekto's own needs. In the movie, we can find that the way Ekto walks is different from other undead, and MiG also imitates his way of walking. Ekto told MIG that the undead would not walk like this. Hector walks with a limp, but most undead walk normally. Moreover, compared with other undead, the skeletons of other undead in Ektoby are more likely to fall apart. Therefore, Hector asked Pigskin to borrow his thigh bone, because he needed to replace his weak thigh bone. After all, Brother Pigskin is about to be completely forgotten. If the living forget him completely, Brother Pigskin will die completely, and the thigh bone will be useless to him. The audience's careful observation also suggests that some bones on Ekto's leg are different from those on the other leg, which may be the thigh bones of pigskin.
Of course, some netizens speculated that Ekto gave Frida Pig's thigh bone, because Ekto wanted to cross the bridge of death to see his daughter, so he wanted to cross the bridge as Frida. Hector gave her the thigh bone of pigskin and asked her to change into a performance costume. In the movie, Hector failed to cross the bridge and came back to Frida to say that he had lost his skirt. Frieda's prototype is a Mexican painter who died in a car accident. His spine was broken into three segments, his cervical vertebra was also broken, and his right leg was severely fractured, so Frida needed a thigh bone made of pigskin. This kind of speculation by netizens is also very logical.
