Tales of the Beanworld
This unnamed thing in the red hat is an unannounced visitor. It showed up one day when the Beans were soaking in the Chowdown Pool. It threatened the Beans with disasters if they didn't cooperate. Mr. Spook wouldn't have any of it and engaged it in battle, with the help of the Spear Fling'n Flank'rs. They seriously damaged it and it fled, but one day may return.
This tale is recounted in the ashcan While We Were Eating.
Professor Garbanzo stored the pieces the thing left behind in her Fix-It Shop. They might come in handy some day.
