If you want to use the Spinbox Machine on the Mobius Circus island in Catch A Monster, you first need to collect five Rubber Ducks. These Ducks are hidden around the island and are required to summon the Jokaire boss. The problem is that the Ducks do not always stay visible because they are shared server spawns, which makes them harder to collect if other players grab them first. To help you save time, here is a complete guide covering every Rubber Duck location, how to get more Ducks using codes, and the fastest way to reach Mobius Circus Island.
Where to Find All Rubber Duck Locations in Catch A Monster
There are five main Rubber Duck spawn points around Mobius Circus Island. Most of them are close to important landmarks, so once you learn the layout of the island, collecting Ducks becomes much easier.
Duck Location 1
The first Rubber Duck is one of the easiest to find on the island. After arriving at Mobius Circus Island, head toward the entrance area near the wooden bridge. You should notice a teleporter nearby along with a yellow-colored tree.
The Duck is sitting right next to the yellow tree close to the entrance path. Since this location is easy to access, many players usually grab this Duck first whenever it respawns.
Duck Location 2
The second Duck can be found near the Spinbox Machine itself. From the center area of the island, look toward the large circus tent nearby. You should spot the Duck sitting at the base of the tent close to the right side of the machine.
This location is usually less crowded than the entrance area, so there is a good chance the Duck may still be available when you arrive.
Duck Location 3
The third Duck is hidden inside the large red circus tent. Starting from the second Duck location, simply walk directly into the tent and continue toward the Lampyr boss spawn area.
You should see the Duck placed on the ground inside the tent. This one is easy to miss because players often focus more on the enemies spawning nearby instead of checking the corners carefully.
Duck Location 4
For the fourth Duck, head behind the large circus tent. You will eventually find a smaller red-and-white makeshift tent hidden in the back area.
Inside the small tent, there is another Rubber Duck waiting on the floor. However, be careful because the Jackpotron enemy frequently spawns around this area. It is recommended to defeat nearby enemies first before trying to collect the Duck safely.
Duck Location 5
The final Duck is located near the giant spinning Ferris wheel found on the right side of the island. This area is more isolated compared to the rest of Mobius Circus, so using a mount can help you reach it faster.
Once you arrive at the Ferris wheel, look near the bottom section of the structure to find the last Rubber Duck.
Other Ways to Get Ducks in Catch A Monster
Besides searching around the island manually, players can also get extra Ducks by redeeming special in-game codes. Currently, the available codes are:
- DUCKA
- JOKAIRY
Each code rewards five Ducks after redemption. To use them, press the gift or rewards icon located at the top-right side of the screen and enter the codes there.
By combining the five collectible Ducks from the island with the ten Ducks from codes, players can get a total of fifteen Ducks. That is enough to use the Spinbox Machine three separate times.
Why Ducks Are Sometimes Missing
Many players think their game is bugged when they cannot find any Ducks, but that is actually normal. The Rubber Ducks work as global server spawns instead of personal loot.
This means if another player collects the Duck before you arrive, the item disappears for everyone else until it respawns again. Usually, waiting around ten to fifteen minutes near the spawn location is enough for the Duck to return.
Changing servers can also help if you do not want to wait for respawns.
How To Reach Mobius Circus Island
Mobius Circus Island is located around 2500 meters behind the starter island. Since the distance is very large, players will need a mount to travel across the water efficiently.
One of the easiest mounts to get early is from defeating the Aquron monster found near the beach on the starter island. After defeating it, players can ride across the water much faster.
Players with Roblox Plus can also purchase the limited-time Dragon Cannelloni flying mount near the Incubation area for 14 Robux. This makes traveling to Mobius Circus much quicker and easier compared to basic mounts.
Collecting Rubber Ducks is currently one of the most important activities on Mobius Circus Island because they are needed to activate the Spinbox Machine and summon the Jokaire boss in Catch A Monster. While the Ducks can sometimes be difficult to find due to shared server spawns, knowing all five locations makes farming much faster. Make sure to redeem the active Duck codes as well so you can maximize your Spinbox attempts and avoid wasting time waiting for respawns.
