DID ANYONE SAY LEARN THROUGH MUSIC!?!?

Ordered on Mercari on the 6th and it just arrived on the 25th... Never buying there again 😒 also the Dora cartridge gets stuck and the Backyardigans cart won't scroll at all (probably thanks to some drink that appears to have been spilled in it long ago). What do you expect for $14 lol. At least I can say Dora's Most Treasured Adventure is A LOT better than the other Dora cart. Expect to hear it soon. Any suggestions on how I can get the Backyardigans cart to at least audibly advance to the other slide would be greatly appreciated. I'm not sure if it's damage to the paper or the actual circuit/contact where the system reads the cart. I never had this happen with a LTM cart before.
