到底是啥啊啊啊啊啊

I am missing one sticker and can't figure out how to get it. It's is the Salmon in the tea cup sticker from Lava Lake. It's the last one I need and I am just so confused.

When I go to the musical bridge and do it correctly at once, I can't cross it. On the other hand, if I'm mistaken and try to solve it again, I don't have the opportunity to complete the puzzle since it's impossible to activate the fourth color. Am I the only one facing this problem? We played it with my daughter and got stuck at this stage. I watched the playthrough, trying to find a step we missed but it seems we did everything properly. Therefore, when we tried to continue, we once again felt so disapp...

显示在最后一关但我找了几遍没找到啊

Queria tanto que esse jogo tivesse conquistas, ele parece bem legal, mas sem conquistas eu fico desanimada de comprar 🤣
