From what I have seen with my own Wublins (and looking at the data supplied by others on this thread), there is no actual earning rate for the Wublins. Due to the glitch with the biggify button they had upon release, you could see that no currency was being gained over time (the collect button you could bring up always had a 0 over it and clicking it did nothing). At the end of a random timer, a random currency is selected with a random amount (except for diamonds, which appear to be locked at 2). There is no set max for the amount to grow to (as evidenced by waiting a longer period of time and still collecting less than what has been collected at another time; feel free to test this yourself), so it is highly likely that it does not grow at all and that it is in your best interest to collect the moment you see that they have something so the timer can start over. In this way, Wublins are similar to mines, in that, when they have currency for you, they will not generate anything until that currency is collected.
