Here what I captured so far, and I tried to use \tcbset to draw the box... and I got a bunch of errors.
EDIT: My current code
\tcbset{/ .style={
colback=yellow2!,
enlarge top by=1cm,
enhance,
breakable,
boxrule=0pt,
top=7mm,
drop fuzzy shadow,
overlay unbroken = {\draw[color=red!80!yellow, line width =3pt]
([xshift=2pt] frame.north west)--([xshift=2pt] frame.south west);
\draw[color=red!80!yellow, line width =1pt]
( frame.north west)--(frame.north east);
\node[rectangle] at ([[xshift=1cm, yshift=0.45cm ] frame.north west)
{\includegraphics[scale=0.06]{imagesInskscape/caracol}};
\node[rectangle, draw=DeepSkyBlue1, fill=DeepSkyBlue1,
font=\LARGE\bfseries, text=white, rounded corners=8pt, minimum width =3cm,
inner sep=1mm, anchor=north west] at ( [xshift=4cm, yshift=0.3cm] frame.north west){ Example};
},overlay first ={\draw[color=red!80!yellow, line width =3pt]
([xshift=2pt] frame.north west)--([xshift=2pt] frame.south west);
\draw[color=red!80!yellow, line width =1pt]
( frame.north west)--( frame.north east);
\node[rectangle] at ([xshift=1cm, yshift=0.45cm ] frame.north west)
{\includegraphics[scale=0.06]{imagesInskscape/caracol}};
\node[rectangle, draw=DeepSkyBlue1, fill=DeepSkyBlue1,
font=\LARGE\bfseries, text=white, rounded corners=8pt, minimum width =3cm,
inner sep=1mm, anchor=north west] at ( [xshift=4cm, yshift=0.3cm] frame.north west){ Example};
},
overlay middle ={ \draw[color=red!80!yellow!50, line width =3pt]
([xshift=2pt] frame.north west)--([xshift=2pt] frame.south west);
},
overlay last ={\draw[color=red!50!black!50, line width =3pt]
( [xshift=3pt] frame.north west)--( [xshift=2pt] frame.north west); }}}
\begin{tcolorbox}[]
\begin{enumerate}

\end{tcolorbox}



\tcbsetand produces errors-we-know-not-which and which may or may not be related. What is the relation between the two images and those images and your code? – cfr Oct 10 '16 at 02:18tcolorboxpackage, so you can start trying to understand similar examples: http://tex.stackexchange.com/a/184530/1952, http://tex.stackexchange.com/a/115605/1952, – Ignasi Oct 10 '16 at 07:36
