How do I plug all the pipes?

I have to fix the plumbing in Beanbag Castle before I can meet the queen. Most of it I can figure out, but there is one room with 4 plugs that is baffling me. I hit the first one, and then I understand I have three more hits to close them all, but since some pop open every time, I can't figure it out. What order do I have to hit them in to get them all closed?

Solution 1:

According to this fan walkthrough on GameFAQs:

Here, you don't even need to guess at the first part, a Spin Jump, but then comes the REAL pain! You can only use the hammer four times to hit the leaks, so therefore, you must hit the leaks in a particular order.

In this order, hit the leaks; Upper-left, Lower-left, upper-right, and then the lower-right leak. After you apply yourself to this, the yellow and black platform will suddenly rise with gushing water, so, two High Jumps and you're off into the next room!
