When Papyrus calls during the chase, the protagonist actually stops moving to answer the phone, and Undyne waits for them.

The water cooler in Hotland was placed there by Alphys, for Undyne.

The reason Undyne doesn't throw spears in the grass or something is because Alphys told them that it has scientific importance, although all she does with it is making ice cream.
