Find a block of text and if a certain keyword exists, remove another block of text within that block

Platform: CentOS Linux
Language: Shell

Hello. So I have a text file named goob, containing the following contents:
Code:
		function-a()=""
                {
			type=scythe
			value-b=true
			{
				under="false"{}
			}
		}
		function-b()=""
                {
			type=hook
			value-b=true
			{
				under="false"{}
			}
		}
		function-c()=""
                {
			type=scythe
			value-b=true
			{
				under="false"{}
			}
		}

What needs to happen is for all functions with type "scythe", I need to remove the whole block of their value-b such that the result would be
Code:
		function-a()=""
                {
			type=scythe
		}
		function-b()=""
                {
			type=hook
			value-b=true
			{
				under="false"{}
			}
		}
		function-c()=""
                {
			type=scythe
		}

Any ideas? Thanks in advance.
