Our limited-time Howl’oween update is live in Backpack Adventure on Roblox. Things that hiss, hoot, and howl are waiting to be discovered! From a Halloween green glow-up and eerie nighttime sounds to a sky-high rope-swing obby and jack-o-lantern headlamp that lights up the night, this seasonal update is packed with creepy-cute surprises for curious kids (and adults!).

But beyond the pumpkins and playful scares, there’s real science hiding in the shadows.
Why Do Animal Eyes Glow?
In real life, many animals’ eyes glow in the dark thanks to a mirror-like layer behind the retina called the tapetum lucidum. It reflects light and helps animals see better in low light — which is why their eyes shine when caught in a flashlight beam or camera flash.
In Backpack Adventure, players can spot the same glowing effect at night. And just like in nature, not all glows are the same.
Some creatures glow green. Others glow red, yellow, or even white. These differences come from variations in eye structure, shape, and the angle of reflection. Players who look closely can begin to recognize which glow belongs to which animal.

That kind of close looking builds pattern recognition and observation skills that translate directly to the real world.
Learning Through Play
Backpack Adventure, was built to spark curiosity about the natural world, and our Howl’oween is no exception. This limited-time event encourages kids to explore big ideas through small, intentional moments of play:
- Light reflection and visual perception
- Animal eye structure and function
- Pattern recognition and scientific observation
- Balance, timing, and problem-solving through obstacle play
Whether they’re spotting glowing frogs near the river, scanning treetops to catch sight of an owl, or swinging high above the forest on the spooky rope swing obby, players are building real science skills — all while playing the game.
And who knows? Their next outdoor adventure might just look a little more magical after dark!
