How can I use ELSE IF inside GROUP_CONCAT?

I have an IF statement inside a mySQL query and it is working well:

 GROUP_CONCAT(DISTINCT CONCAT("animal:",if(animal.name="monkey","fred",""),",color: ",animal.color) SEPARATOR " <br>") AS animals

I want now add an ELSEIF:

  GROUP_CONCAT(DISTINCT CONCAT("animal:",if(animal.name="monkey","fred","")elseif(animal.name="cat","jane",""),",color: ",animal.color) SEPARATOR " <br>") AS animals

But I get an ERROR message:

Syntax error or access violation: 1064 You have an error in your SQL syntax
