第二天训练课上，老师就带来了两首新歌交给cat组合，一首中文歌，一首英文歌。中文歌叫做《舞鞋》，英文歌叫做《cat》。

窗外的蝴蝶，随风翩翩舞，落在了我的舞鞋上

我的红舞鞋，就像一盏灯，照亮了前进的方向

前进的路上，有只小精灵，陪着我快乐的歌唱

我们手牵手，我们放声唱，将我们心中美好唱响

我就是倔强倔强，我就是骄傲骄傲，仰起我微笑的脸庞

不要让皇冠掉落，不要让眼泪流下，我的世界由我主宰

跳舞吧，开心跳起来，将自己心中烦恼释放

跳舞吧，开心跳起来，像花儿一样美丽绽放

哦哦哦释放释放，哦哦哦绽放绽放，每个人都要告诉自己很棒

哦哦哦释放释放，哦哦哦绽放绽放，每个人都是自己的宝藏

哦哦哦释放释放，哦哦哦绽放绽放，每个人都要告诉自己很棒

哦哦哦释放释放，哦哦哦绽放绽放，每个人都是自己的宝藏

Get up in the m pass by the garden

Playing with Hedgehogs

Running with Groundhog

Returning home， covered in dust

They doted me in their hands
