Ужасная анимация формы регистрации по эмаил с надгробиями

Возможно с помощью данной ужасной анимации email формы с надгробиями кто то захочет украсить свой проект к Хелоуину, а возможно у кого то тематический ресурс и данная форма регистрации будет красивым или ужасным дополнением. Данный фрагмент кода содержит в себе жуткую анимацию формы подписки (регистрации)  в виде призрака и надгробия. Суть заключается в том , что после ввода email адреса, он как бы покрывается кровью, плавно переходит в гроб который уходит под землю, а после появляется призрак и надгробие. Ниже привожу код страшной анимации для сайта.
