Minecraft cake green grass, potato ricer?

[Seven8nine]

Hi
DS wants this cake for his birthday, the recipe on this one uses coloured coconut shreds for the grass, DS doesn't like coconut.
Anyone know if I can put green icing through a potato ricer (I'd have to buy one) to get this effect? Or any other ideas?

Thanks

You can get a grass piping nozzle (Wilton 233, 234 or 235 depending how thick you want the grass) - probably cheaper than a potato ricer

Amazing thank you!
