The makka of Oraiv(mixture of animals) the passuk says the animals filled the homes of the mitzrim and they came with their land upon which they are.
There is a mishna in klayim(8:5) which refers to an animal called the adnei hasadeh,which according to some meforshim it is the creature called the yidoa which is half animal half plant. It has human like features and is connected to the ground with an umbilical cord .If the cord gets detached from the ground it dies. Now the passuk can be fully appreciated when it says it came with its ground, because even this animal came .(Rav Shimshon of Ostropoli)
