The word "Krokodilli" doesn't come from your query, it comes from your data - and it's in the column that you are trying to compare.
We can't see your code - or your data - so we can't tell you exactly what to do to fix this, but part of your WHERE clause is causing SQL to try and convert your column to an integer value and failing.
Look closely at it, and try putting quotes around any litteral values you want to compare, or using CONVERT to change parameter values to NVARCHAR for comparison:
