Golden Rubber Duck at Lucua's Climb

[Jo_The_Plumber]

So I just finished the Void Lucua's climb, and was about the leave the portal when I saw this random rubber duck. There is a cave to the side the fountain that the portal is on, and it's just chilling to the side. I managed to jump over to it, but there is nothing to do. It's just a random rubber duck. Any info on this? Is it just a random Easter egg?

I found 2 as well. On on the rafters in the steam room were the elevator is & the other by the statue that wants the odd rock. I have no idea what they are for either.
