Hodgkins and Moominpappa uses Edwards extreme size to their advantage when they launch the Oshun Oxtra, by tricking him into taking his Saturday bath in the river instead of the lake. This causes the river to overflow, taking the Oshun Oxtra along with it. However, Edward has very sensitive feet and rear, which get hurt when he sits down on the sharp rocks of the river floor. He then tracks Moominpappa and his friends later on in the story, most likely planning to flatten them, but changes his mind when he receives a soft cloud to use as a pillow. Towards the end of the story, Edward unknowingly saves the crew from a terrifying sea monster by stepping on it.
In the Tales from Moominvalley short story The Hemulen Who Loved Silence, Edward makes a cameo appearance, where it is mentioned that he wins first price in porceline destruction at the Hemulens theme park.
