Question: Plot curve in 3D

Hi! I need some help with a curve I'm trying to plot.

f(x,y)= x^2*y^2/(x^4+y^4)

I'm asked to intersect the surface produced by f(x,y) with the plane z=1/4 and to plot the curve generated by the intersection (in 3D). I found how the curve looks like but I don´t know how to plot that in 3D.plots[implicitplot]( x^2*y^2/(x^4+y^4)=1/4,x=-3..3,y=-3..3)


That's all I've got so far.
