奶蛙 - 点一下就狂笑抽象魔性

Just click, and that's enough.
The milk frog stands there, quietly. You click on it - it starts laughing wildly. Doubling up with laughter, trembling, out of breath, laughing so hard that the whole body is shaking. Finally, it laughs itself into a faint.

Click to laugh
Click on the milk frog and watch it go crazy on the spot. Click again while it's playing to start over. Electronic wooden fish, cyber chanting.
Loop and laugh
Turn on the loop mode and the milk frog never stops. The infinitely looping crazy laughter is suitable for mental output in group chats and also suitable for brainwashing oneself repeatedly.
Warning: This app is highly contagious. Side effects include, but are not limited to: laughing无故 in public, unable to stop playing 47 times in a row, and sending it to everyone you know. （注：“无故”这里直接用拼音“无故”，因为在中文语境下比较好理解，但英文中没有完全对应的词，这样处理更能保留原文风格，若有更合适的英文表达可替换）
