Frog Rush

You are an elite scientist working at a secret lab! It wasn’t your fault that the spill happened and contaminated the local lake with toxic chemicals, and made all the frogs into killer amphibians! OK – maybe it was but we all have our off days.
But now you need to solve the problem and DESTROY ALL FROGS. You can do this by drip feeding the frogs some precious “Chemical K”. The frogs love this and grow larger with each drop until fully primed and “SPLURGE!” they explode shooting lethal frog blood all over the place. Any frog hit, if primed, will explode too so you need to ensure the perfect chain reaction using the tiny amount of Chemical K you have available.
