  Due to the chocolate sponge is too soft to handle, cut the sponge cake into half.

  125g Semi sweet chocolate
  20g Butter
  90g Whipping cream
  
  Chop semi sweet chocolate into smaller pieces and put it in a bowl together with the butter.
  Boil whipping cream at medium heat and pour on the chocolate pieces. Use hand whisk to stir till chocolate melted and smooth, leave to cool.
  Put ganache cream in fridge for few mins till semi set, stir well and spread on sponge cake.
  
  Assemble:
  Place the tiger skin sponge (skin facing down) with a large baking sheet below.
  Spread ganache cream evenly on it and place the two half chocolate sponge on top vertically side by side. Spread another layer of ganache cream on it ~not too thick~ then roll it up and wrap with the baking sheet.
  Put the roll in the fridge for the ganache cream to set for about an hour.
  Dip your knife in hot water and quickly dry it off before each cut.
  
  Kitchen note: Can use butter cream or jam to substitute the chocolate ganache cream as you like
