The Grow Ray is an item that, when shot at mobs, makes the size of the given mob increase. You can obtain it from Sneaky Sal or as a drop from Growbot Gregg. It is the opposite of the Shrink ray, and can be used on pets to make them bigger. There is a bug with the hitboxes of mobs that you can ride on, like the camel, the zebra, the rocket giraffe, and the pony.
