In the module where you edited text "Spielend lernen im Internet.", you should have this HTML (after div.header):
Code:
<div id="bee1"></div>
<div id="bee2"></div>
<div id="balloon1"></div>
<div id="balloon2"></div>
<div id="balloon3"></div>
That's 5 empty div's with appropriate id's. If you WYSIWYG editor is cleaning this code when you edit this module, then disable the editor from Global configuration before making edits.
