Getting Puzzle Pieces for Himespetchi in Tamagotchi P

Hi. So I finally got a Himespetchi. I got it while using the Nameko Pierce. I played a lot of games just so I can buy the living room wall papers and try them out and to by the Nameko cultivation kit. So in return, I got Himespetchi. I so far got 3 puzzle pieces. One for putting on the Nameko Accessory on Himespetchi, which was very surprising, one for the drink it likes and another for using the hand mirror. Now I though, Himespetchi also got a puzzle piece or the lab coat/white uniform. So I go and buy one and put it on Himespetchi and nothing happened. I got the information for what my tama likes here:

Does anyone know for sure?

You need to wait 48 hours to get the last piece

Oh okay. Thank you. Wow. So many little tamagotchi rules. Very interesting. Thank you again.
