Monster Castle is episode thirty-eight of season two of Hero: 108, and episode ninety overall.
- According to Woo the Wise, this episode takes place on the summer solstice, the longest day of the year and beginning of astronomical summer.
- Woo mentions "Commander ApeTrully and the rest of the animal kings" in such as a way seems to indicate that ApeTrully is an animal king, a fact which Woo was not believed to know. However, it is possible that the implied excepted animal king was intended to be Jumpy.
